8d05659074 Limit arrays to a maximum of eight dimensions.
This addresses a sanitizer issue discovered in
https://oss-fuzz.com/testcase-detail/4908118777266176 (it has not been
assigned an oss-fuzz bug number yet; coming soon)

We need to set some sort of limit here to avoid stack overflow. Eight
array dimensions seems like more than enough for any sort of code that
we might realistically need, but the limit is definitely flexible if we
wanted to increase it. (The fuzzer needed to generate a several-
hundred-dimensional array before encountering a crash.)

9e2544e62f Add unit test for array with many dimensions.
This addresses a sanitizer issue discovered in
https://oss-fuzz.com/testcase-detail/4908118777266176 (it has not been
assigned an oss-fuzz bug number yet; coming soon)

A followup CL will limit array dimensionality to 8. This is an arbitrary
choice which is hopefully larger than any reasonable program will need.

0ad52f6a24 Add unit test for fuzzer-detected error with in vars.
`in` vars shouldn't support initializer expressions at all. The fuzzer
noticed that dead-stripping interacts poorly with `in` var initializer
expressions, which makes sense because it's an unsupported and untested
path. In a followup CL, lines 1 and 3 will both become errors.

71624de2c5 Allow constant propagation for negated constant-vectors and ints.
This CL improves on the previous fix for oss-fuzz:26789 by actually
propagating the negation from the PrefixExpression inside the
constructor, which unblocks further optimizations.

Interestingly, this fix also exposes a further missing optimization--we
optimize away comparisons of constant-vectors for floats, but fail to
do the same for ints.

569249be6c Improve support for function prototypes in SkSL.
Previously, when a prototype was parsed, this added a function
declaration to the symbol table, but the prototype itself was not
re-emitted during code generation. This meant that the final code might
not be valid, since the absence of prototypes meant that the code might
attempt to invoke a function before its declaration. Now, prototypes are
stored in the ProgramElement list and re-emitted during code generation
for GLSL/Metal/CPP. (SPIR-V doesn't name its functions at all.)

c3cb099556 Add GrVx.h
Adds grvx, Ganesh's addendum to skvx. Here we introduce familiar names
and operations from GPU languages, as well as functions that are
approximate and/or have LSB differences from platform to platform.

The initial implementation has: fast_fma, fast_acos, and
fast_angle_between_vectors. When a function is approximate, its error
range is well documented and tested.

Also establishes GrWangsFormula as the first user of grvx.

Currently, the prototypes are not actually emitted in the generated GLSL

proper prototype support is added.

67e1cf4b1d Replace pooling mechanism with GrMemoryPool.
This change is a wash for tests that could fit inside the previous
hard-coded pool (512 nodes) and appears to be a 5% improvement for
sksl_large. Larger programs would hypothetically show an even more
significant improvement.

When SK_SUPPORT_GPU is disabled, we disable pooling entirely and fall
back to the system allocator. This is necessary because SkSL can exist
without Ganesh (such as in the wasm+CanvasKit build).

8744a5c820 Add unit test for nested function calls in FP files.
`func1` and `func2` emit bad code, `return %s()`, and because they don't
consume their `%s` format argument. This leaves the format argument list
unbalanced and all future args are wrong.

Another serious problem is that we don't actually know the names of the
functions that they need to call, because we haven't emitted them yet.

`func3` is not emitted at all. Sampling from a fragment processor
apparently fails in this context.

This is a more general case repro for skia:10684--it turns out that
recursion in particular wasn't the issue, but nested function calls just
don't work properly at all in FP files. This wasn't an issue in practice
because we don't have any existing FP files which nest function calls,
and the inliner also tends to aggressively flatten everything out if we
don't explicitly disable it.

This brings back the basics from SkSLFPTest.cpp. This file was removed
entirely in http://review.skia.org/319029 but, in retrospect, it's still
a good idea for dm to verify that CPPCodeGen and HCodeGen can do their
jobs. And, like SkSLGLSLTestbed, this gives us a good place to attach
the debugger in dm for testing CPP/H-specific code generation bugs.

9cef66fbf5 Fix use-after-free discovered by fuzzer.
In cases where multiple variables were declared on a single line, it is
legal for variable initialization-expressions to reference variables
declared earlier in the var-decl statement. It is NOT legal for the
inliner to move those references up to the previous statement, where the
variable doesn't exist yet.

This is mitigated by disabling the IRGenerator inliner for var-decls
past the first one in a var-decls statement. (The optimizer will still
pass over this code later and is able to inline it correctly, if it is
worth doing.)

(In C++, and consequently in Metal, these expressions are considered
legal by the grammar and do compile, but generate garbage output.)

e16eca95f5 Create a basic IRNode pooling system.
Allocations are redirected by overriding `operator new` and `operator
delete` on the IRNode class. This allows us to use our existing
`unique_ptr` and `make_unique` calls as-is. The Pool class is simple;
it holds a fixed number of nodes and recycles them as they are returned.

A fixed pool size of 2000 nodes was chosen. That is large enough to hold
the contents of `sksl_large` during compilation, but it can be
overflowed by very large shaders, or if multiple programs are converted
at the same time. Exhausting the pool is not a problem; if this happens,
additional nodes will be allocated via the system allocator as usual.
More elaborate schemes are possible but might not add a lot of value.

Thread safety is accomplished by placing the pool in a `thread_local`
static during a Program's creation and destruction; the pool is freed
when the program is destroyed. One important consequence of this
strategy is that a program must free every node that it allocated during
its creation, or else the node will be leaked. In debug, leaking a node
will be detected and causes a DEBUGFAIL. In release, the pool will be
freed despite having a live node in it, and if that node is later freed,
that pointer will be passed to the system `free` (which is likely to
cause a crash).

In this CL, iOS does not support pooling, since support for
`thread_local` was only added on iOS 9. This is fixed in the followup
CL, http://review.skia.org/328837, which uses pthread keys on iOS.

Nanobench shows ~15% improvement:

a80a3dc170 Fix frexp support in Metal.
Our Metal codegen assumes that out params are pointers, but Metal's
built-in frexp actually takes a reference for the exponent, not a
pointer. We now add in a helper function to translate.

Don't skip deps from modules/.  The initial exclusion was added long
ago, when Skottie deps were causing build issues.

Now it doesn't seem to be needed anymore, and it actually gets in the
way (see exceptions for various modules).

6aaecfb7f7 Update image filter debug samples to use new APIs
For clarity, this renames skif::Mapping::Make to skif::Mapping::DecomposeCTM
to really emphasize when it should be used over just a constructor.

Renames SampleBackdropBounds to SampleFilterBounds since the operations and
coordinate spaces that it visualizes are the same for regular or backdrop
filtering (we just swap the notion of src and dst devices, really).
Technically, this is not quite true yet since regular filtering modifies the
DAG with a matrix transform right now, but that's going away soon (tm).

The "new" SampleFilterBounds example is updated to use the new bounds APIs
that use the coord-space safe types in the skif namespace. It also visualizes
a filter, and simplifies some of the bounds being drawn and reported to
only those most interesting.

The SampleImageFilterDAG has been updated to match the soon-to-be state
of how SkCanvas processes regular image filters for a saveLayer. All
implicit matrix-transform node code is removed. The bounds calculation
code is similarly updated to use the new 'skif' types and functions. To
simplify the visualization of each node, the 'isolated' versions of the
bounds were dropped.

8dbdf23f31 Remove two uses of setModifiersHandle
As a prelude to going back to sharing global data (safely), we want to
eliminate as much mutation of shared state as possible. The special
cases for global variable declaration were unnecessary, so just remove
them. The editing of main's parameters immediately after they were
created is also unnecessary - just hoist the logic up so we create the
variables correctly in the first place.

There is still one use, related to invocation ID. That's more
complicated (?), so leaving it as a separate CL.

7d0f853158 Add SkImageFilters::Shader in place of Paint factory
SkImageFilters::Paint did not use every slot of the SkPaint, with only
its color, alpha, color filter, and shader having a meaningful effect on
the image filter result. It was always blended into a transparent dst,
so blend mode wasn't very relevant, and it was always filled to whatever
required geometry, so stroke style, path effect, and mask filters were
ignored or not well specified.

Color, alpha, and color filter can all be combined into an SkShader, so
a more constrained SkImageFilters::Shader provides the same useful
capabilities without as many surprises.

SkImageFilters::Paint still exists, but is deprecated to be removed
once I've confirmed clients aren't depending on it.

796cdb7839 Use SkTHashMap to implement DefinitionMap.
The benchmarks show a negligible performance decrease over the bespoke
TinyUnorderedMap class, but it's well within the margin of error, and
a real hash map will scale better in pathological cases.

c021360a88 Only include one variable per declaration statement
This removes VarDeclarationsStatement entirely. VarDeclaration instances
appear directly as statements in Programs. SkSL that declares multiple
variables in a single declaration is transformed to represent that as a
series of VarDeclaration statements.

Similarly, global variable declarations are represented by
GlobalVarDeclaration program elements, one per variable.

49a547f7e2 Separate out SymbolTable aliases from regular Symbols.
SymbolTable::addAlias can be used to create a Symbol that's an alias for
an existing symbol, but uses a different name. (e.g. in Runtime Effects,
a `fragmentProcessor` is a `shader` and `float4` is also `vec4`.)

SymbolTable::addWithoutOwnership will now assert if an attempt is made
to add a Symbol with the wrong name. In a followup CL, the name argument
will be removed entirely and it will simply use the Symbol's name.

Our code relies on std::unordered_map for storage of unordered data.
Unfortunately, while unordered_map is algorithmically quite efficient,
in many real-world scenarios--particularly with small amounts of data--
a simple vector with linear search runs rings around it.

This CL doubles the performance of `nanobench -m sksl_large`:

0eca74cd2c Move bytesPerPixel query off of GrCaps and add bytesPerBlock query.
Part of this change is to move some of this static format information
off of GrCaps since it is not cap dependent in anyway. This allows us
to the need for caps in many places. Also changes the low level format
query to be based off of bytes per block so it can be shared for
compressed and non compressed formats.

This change will also make it easier to add stencil/depth formats in
follow on change since we don't have to fill in a whole caps
FormatInfo block just so we can get the bytesPerPixel which is all
they need.

c14defb8bf Disallow assignment to unfoldable ternaries in SkSL.
GLSL does not support assigning to ternaries, and will fail to compile
and/or generate non-functional shaders if we pass in a shader that tries
to assign into a ternary expression.

If SkSL is able to completely eliminate the ternary (e.g. if it boils
down to a simple `true ? x : y` or `false ? x : y`), SkSL can strip out
the ternary entirely and generate valid GLSL. This case is harmless and
so it is still allowed.

These tests will also be used for Metal and SPIR-V testing. A small
handful of GLSL-specific stragglers (#version-specific or type-precision

5d9d837994 error on the side of safety for empty blobs
If the blob is empty, then try to regenerate it. Using
this method caused a slowdown in Skia perf, so we
added an extra check to allow some empty blobs through
for perf performance. The perf problem was caused by
SKPs generate empty blobs because of font mismatches.
Flutter has shown that scaling from very small to
normal size is not correctly handled by the existing
check. This CL favors correctness over optimizing empty
text blob and always regenerates empty blobs.

0ed9f31f6a Migrate several GLSL workaround unit tests to golden files.
We now support building an SkSL golden output twice, once honoring the
custom #pragma settings, and once more ignoring the settings. This
allows us to see the output of the workaround technique, alongside the
"default-settings" output which should not contain a workaround.

To implement this, skslc now supports a flag: --[no]settings.
When it's set, /*#pragma settings*/ comments are honored. When it's not
set, skslc ignores the comments. compile_sksl_tests.py passes this flag
along to skslc.

This approach is not strictly limited to workarounds; the
"TypePrecision" GLSL test was also updated to use this technique.

a195d101f9 New GrClipStack supporting only intersect/difference
Overview doc: https://docs.google.com/document/d/1ddIk74A1rL5Kj5kGcnInOYKVAXs3J2IsSgU5BLit0Ng/edit?usp=sharing

This is the new clip stack that will replace GrClipStackClip. The doc
link in the CL description has a much more detailed overview of what the
strategy of the new clip stack is, but at a very high level:

1. Add a temporary #define that lets SkGpuDevice switch between the old
stack and the new stack. For the new GrClipStack, it extends SkBaseDevice
directly and has to implement all of the device clipping virtuals.
   - If you look from patchset 5 and earlier, the define defaults to on
     so I can test it on the bots, etc. but the plan will be for it to
     default to off when this lands so it's only running on unit tests.
     Then in a follow up, I'll turn it on for our bots but keep it off in
     chrome and android. If everything looks good, chrome can then be
     turned on. There is a more extensive migration plan for android
     because of the expanding clip ops, but that is covered at the end of
     the overview doc.

2. GrClipStack manages save/restore logic of the stack and extends GrClip,
so the cpp file also includes code to apply a GrAppliedClip. At the moment
the apply strategy is as close to that in GrReducedClip and
GrClipStackClip as I could make it. Down the road, I think we can explore
other analytic coverage options and a clip atlas that replaces the unified
SW mask.
   - Once GrClipStack is enabled everywhere, it means GrReducedClip and
     GrClipStackClip can be deleted, so I'm not too worried about sharing
     code between the two. A lot is already shared through the use of
     GrSWMaskHelper and GrStencilMaskHelper.
   - SkClipStack and SkClipStackDevice are still used by the PDF and SVG
     backends, so they aren't necessarily deletable.

3. The GrClipStack only handles intersect and difference ops. It
represents all geometric clip operations as an element. The stack itself
is controlled by the "save record", which tracks aggregate bounds, valid
elements, and the non-geometric clip shader.
   - When a new save record is pushed on the stack, older elements are
     inactive. This means they cannot be modified, since they may need to
     be activated again when the current save is popped off the stack.
     However, they can still affect the clip during application.
   - When a new element is pushed on the stack, older elements may be
     invalidated. This means they don't need to be considered any more
     because they are redundant with the new clip shape (e.g. nested round
     rect clips only have to keep the innermost valid).

d911c91d88 Normalize line endings in SkSL error tests
On Windows, the process output contains CRLF sequences. Calling
splitlines() recognizes those (Python universal line endings), so we get
a list of the output lines. Joining those with '\n' produces a string
that just has LF. (We add another one, so we still end the file with a
newline). Because we've opened the file in binary mode, the resulting
files now look the same, regardless of OS.

f2cdf59d58 Migrate SkSL inliner tests to golden files.
Our lack of proper caps-bits controls in skslc affects the outcome of
one test: "InlinerWrapsEarlyReturnsWithDoWhileBlock" does not actually
emit the do-while block because the standalone caps bits don't enable
do-while support. This will be fixed in a followup CL that adds caps-bit
support to our tests.

A few tests were renamed for consistency, a few were simplified slightly
and one test was removed because it was simply redundant (there was a
second test that covered the exact same ground as
`ForWithReturnInsideCannotBeInlined`).

272e8bcd24 [fuzz] Add libfuzzer binaries to BUILD.gn
For the longest time, the libfuzzer binaries used by oss-fuzz
were just hacked onto the BUILD.gn file. This removes that patch
and makes them buildable from Skia proper.

After this, there should not be any modifications oss-fuzz needs
to do to a Skia checkout before it builds and runs.

Of note, oss-fuzz will define skia_use_libfuzzer_defaults to be
false so it can control those flags with more finesse (e.g.
fuzz with ASAN, fuzz with hong fuzz instead of libfuzzer). I
added on skia_use_libfuzzer_defaults so that a normal developer
gets something that works by default.

8f026259d8 Demonstrate name reuse error in inliner.
The following conditions lead to the error:
- A pair of nested functions, both of which must be inlined.
- Both inlined functions create a variable with the same name.
- The outer function passes its variable to the inner function.
- The initialization of the inner variable uses the value from the outer
  variable.
- The inner function does not mutate the variable, use it as an out-
  parameter, or otherwise cause it to receive a temporary copy.

When all these conditions are met, both variable declarations are
inlined as-is without performing any name salting, because it's
seemingly safe to do so. The name overlap issue is not considered in the
safety checks. Inlined variable declarations are not subject to name
salting but they should be; I suspect other adversarial examples could
be crafted as well where unhandled name overlap leads to errors.
