fd36683fe6 Improve parser behavior with invalid statements inside a Block.
Previously, when the parser found a bad statement inside a Block, it
would stop processing that Block entirely. This caused our brace
matching to fall out of balance. block() would normally only return once
the Block's closing brace was consumed, but in this case, the closing
brace would still be in the parse stream awaiting consumption even
though block() had returned.

Now, when a bad statement is found inside a Block, we just ignore it and
continue processing. (I tried injecting a poisoned statement as well,
to see if it would affect the test results, but they were identical.)
This seems to generate somewhat better errors.

1f813e4c7f Fix parallel array length mismatch in test.
In the recently introduced FontConfigInterface_MatchStyleNamedInstance
test the highBitsExpectation vector was one bool too short. Because this
was a std::vector<bool> AddressSanitizer because as silent because all
the bits fit in one underlying storage unit. It isn't clear why
MemorySanitizer did not seem to catch this. In any event,
highBitsExpectation[6] was effectively a random causing the test to fail
about half the time.

Restructure these parallel arrays into a Test struct so that the
expectations are obvious and line up. Also make everything constexpr.

9cb74e9079 [bazel] Compile gms for wasm and WebGL
PS 1 is re-generating existing BUILD.bazel files
PS 2 is generating BUILD.bazel files for tests/gms
PS 3+ makes modifications to build all of the gms and tests.

It is recommended to view this CL with just a diff between
PS 2 and the end, due to the large amount of generated changes
in PS 1 and 2.

We make a filegroup for the gms and tests because they need
to be compiled as one large blob in order for the registries
to work. Maybe in the future we will break these up, but at least
for WASM/JS, the overhead of starting a browser for each new
test would likely grind things to a halt, so we just group them
all together for now. It's also the most similar to what we
currently do.

In gm/BUILD.bazel and tests/BUILD.bazel, we add a cc_library
that encapsulates all of the deps of the tests, so we can
easily include that the build. These were discovered via
trial and error, not anything automatic or systematic.

The is_skia_dev_build config_setting is very similar to the
GN equivalent from which it was based.

The list of gms and tests to skip (e.g. which are incompatible
with WASM) was determined by building the wasm bundle:

modules/canvaskit$ make bazel_gms_release
tools/run-wasm-gm-tests$ make run_local_debug
# Don't forget to click the button on the screen after the
# browser loads

This way of invoking the tests will be replace soon with
`bazel test <something>`. As such, I didn't bother fully
documenting the current way.

Suggested review order:
 - modules/canvaskit/BUILD.bazel taking note that we always
   use profiling-funcs to make the stacktraces human readable.
 - gm/BUILD.bazel and tests/BUILD.bazel to see the lists of
   gms/tests. Notice the tests are roughly partitioned because
   we don't support things like vulkan/PDF in the wasm build
   and we will want a way to not build certain tests for
   certain configurations
 - tools/* noting some of the cc_libraries added to make
   dependencies easier to add when needed.
 - All other files.

72941b87f0 Group arrays/structs together in the variable pane while debugging.
SkVMSlotInfo now contains a "group index" field in each slot. The
group index starts at zero for the first slot of a variable and
increases by 1 for each slot associated with that variable.

For simple types, this group index will always match the component
index. (This is by far the common case, so the groupIndex field is
omitted from the JSON if the indices match.) For more complicated
types--structs, arrays, or nested combinations thereof--it gives us
a simple way to find the start and end slot of a variable. For a given
slot, we can identify the associated variable's initial slot by
subtracting its group index, and we can identify the last slot of any
variable by walking forward and looking for a group index of zero
(indicating the start of a new, different variable).

d6f7e294e8 Better report lack of SkSVG in test.
The `Typeface_glyph_to_char` test assumes that
`ToolUtils::emoji_typeface()` will always return an SkTypeface which
supports all the codepoints in `ToolUtils::emoji_sample_text()`.
However, it is possible in some configurations for there to be no
available emoji font. Detect this and provide a better massage about why
the test failed.

Correct the preprocessor directives in TestFontMgr.cpp so that the
"Emoji" and "Planet" test fonts are consistently defined and used.

a424b619bc Fix OverflowFloatLiteral test in OS X 10.12.
std::stringstream has a subtle bug in OS X 10.12. Reading in a too-large
floating point value returns INFINITY but does not set failbit. This
caused SkSL to report a different error message than expected
("floating point value is infinite" instead of "floating-point value
is too large: NNNNN"). We now guard against this case in SkSL::stod by
adding an explicit `isfinite` check.

b86ab9d097 Improved symbol handling in whole-program serialization
Previously, a dehydrated SkSL program would include all symbols, even
module builtins. The rehydration API also required a vector of shared
elements, which made the API essentially impossible to use outside of
the very artificial situation in our test cases, where we retained the
original program so we could simply grab the elements from it. We
obviously cannot rely on the original program still being around in
order to successfully rehydrate it.

This CL eliminates the parent symbol tables, referring to module
builtins by name instead. This reduces the size of a small dehydrated
program by roughly 95%. We also encode the shared elements directly
into the output, which both simplifies the API and makes it work in
real-world cases.

d0234ba3bf Move backend-specific error tests out of errors/ test folder.
These tests only generate an error in the SPIR-V or GLSL backends. We
will soon enforce that everything in errors/ must actually fail to
compile.

88ddcb8f50 Reland "Pin FcConfig for FCIDirect at creation."
This reverts commit d7f7cc8791.

SkFontConfigInterfaceDirect class methods used the FontConfig library
static global "current" FcConfig (implicitly through the use of
nullptr). This was pinned down once per call to each method which used
it (to avoid the "current" FcConfig from being changed out from under it
while running). However, the use of global state as a matter of course
makes it very difficult to reliably test.

Modify SkFontConfigInterface to optionally take an FcConfig on
contruction. If nullptr is provided it is equivelent to the old behavior
so that existing users are unaffected. SkFontConfigInterface takes
ownership of any passed FcConfig and will release it on destruction.

87aa7a9095 Add SK_PRINTF_LIKE to existing variadic print functions.
This shook out a handful of formatting issues:
[SkVMVisualizer]
- We were passing plain text like "width:35%;" through printf.
- One particular opcode type was printing a string as a number.
[Skottie, SortToy]
- Used wrong integer type instead of %zu for size_t

This CL does not update print functions which take printf arguments via
variadic template, as __attribute__((format)) does not support this
style. These could be converted to va_list style, but that's not done in
this CL.

(For some reason, GCC requires the attribute to be set on a prototype
for freestanding functions, so a few of these now have a prototype
immediately followed by a declaration.)

bee5ccd548 Avoid "drawable" when not referring to SkDrawable.
Change all use of "drawable" to "accepted" in glyph drawing code. To
improve uniformity "rejects" is also changed to "rejected".  This is
motivated by the desire to add SkDrawable backed glyph rendering, which
would make the use of "drawable" for both "glyphs which are drawable"
and "glyph which renders with SkDrawable" very confusing.

8405dfceaa Improve remote glyph caching.
A glyph cache entry is made up of metrics, an image, and a path. If an
entry does not exist then nothing is known of the glyph yet. If there is
an entry it must have at least the metrics. The image and the path may
logically be added lazily as needed. Prior to this change it was not
possible to send both the image and the path of a single glyph. The
added test fails when a given strike is used for both the image and the
path. With this change the test passes, as the image is sent and the
path is sent, and both are merged into the remote glyph. The assertions
around not creating the glyph more than once are replaced with
assertions that no part of the glyph is set more than once.

995d16fc91 For runtime shaders, deduce isOpaque automatically
The forceOpaque parameter is now ignored. Instead, we do a conservative
analysis of the shader's main function to determine if it always returns
an opaque color. This is good enough to detect simple cases, including
things like:

  return child.eval(p).rgb1

ffeb6f2339 Remove SkSL::String class.
The previous CLs have removed the last significant differences between
SkSL::String and std::string. This CL removes SkSL::String entirely and
replaces it with std::string throughout the code.

Apologies for the very long CL, but I have done my best to make it as
simple and reviewable as possible. The vast majority of changes are
simple replacement of `SkSL::String` with `std::string`. In the rare
spots where code is moved from one place to another, it is logically
unchanged.

55a69d1de0 [graphite] Store ResourceProvider on Recorder instead of Gpu.
By being on Recorder, more calls can directly access the ResourceProvider
without needing the Context or Gpu. A different ResourceProvider is
created for each Recorder. Each ResourceProvider stores a ref to the
GlobalCache so that it can access shared resources. Eventually each
ResourceProvider will also have its own ResourceCache for all non shared
Resources.

A big win of this change is that Context can be removed from Recorder.

805acda3f3 [fuzzer] Remove GL from (now-Vulkan) build
The fuzzer runs against the Vulkan version of Swiftshader.
There are no libGL.so (etc) on the fuzz runtime, so we
want to avoid linking against those.

The GL code that is #ifdef'd out is still necessary to
avoid timeouts on TSAN with our NVIDIA jobs.
https://skia-review.googlesource.com/c/skia/+/502638

Procedure for testing this locally (and iterating):
  1. In oss-fuzz checkout, run
     `python infra/helper.py shell skia`
     to pull up local interactive version of Docker
     fuzzer build image.
  2. Run `compile` in fuzzer shell. Stop after
     the swiftshader compiles and is copied into /out
     with Ctrl + C.
  3. Comment out the swiftshader compilation part [1]
     (no need to re-do this when modifying Skia code).
     `apt-get install nano -y`
     `nano ../build.sh`
  4. Make change to Skia repo using normal methods.
  5. Run the following in the Skia repo
     `git diff origin main > foo.patch`
     Copy the patch into the Docker shell using Ctrl+C
     and nano.
  6. Apply the patch inside the Docker shell
     `git apply foo.patch`
     and re-compile (which should skip right to
     building the fuzzer libs)
     `compile`
  7. Repeat 4-7 or make small changes directly in
     the Docker shell via nano.
  8. When compilation and link succeeds, run
     `ldd /out/api_mock_gpu_canvas`
     to verify GL and friends were not dynamically linked.

This class will be used to provide thread safe access to various shared
resources in Graphite. Currently the only thing moved onto here is
the SkShaderCodeDictionary. Eventually it will have things like the
pipeline cache on it as well.

The plan is that users will not access this class directly but instead
via a ResourceProvider (see follow on change).

The test does not exercise width or slant.

Add a small (~8.5k) subsetted Noto Sans CJK collection as a test font
(made using [1]), and ensure that matching, reported font style and axis
configuration are correct after matching.

260d925cb3 Optimize SkVM approx_powf for simple cases.
Our SkVM code generator will always convert `pow(x, y)` into an
`approx_powf` call. However, in many cases, `x` or `y` might boil down
to an immediate value, and for some immediates, we can reduce the
operation into something much simpler:

- `pow(1, y)` is always 1
- `pow(2, y)` can be converted to `approx_pow2(y)`
- `pow(x, 0.5)` can be converted into `sqrt(x)`.
- `pow(x, 1)` can be converted to `x`
- `pow(x, 2)` can be converted to `x * x`

We could go further if there is a need, e.g. `pow(x, 4)` can become
`a = x * x; return a * a`, but these seemed like the best places to
start.

c3d8062555 Fix up SkSL test on Wembley.
Test "InlinerHonorsGLSLOutParamSemantics" was failing on Wembley devices
and is now disabled on that GPU.

Also, it turns out that the inliner has ignored functions with out
params for a long time now, but our test names haven't been updated to
account for this. So, did some additional cleanup:
- "InlinerHonorsGLSLOutParamSemantics" (the test in question) has been
  moved to shared/ and renamed to "OutParamsAreDistinct."
- Removed test "OutParamsNoInline" as it is functionally the same as
  "OutParams".

343258fa0c Fix fuzzer-discovered error with sk_SecondaryFragColor in SPIR-V.
sk_SecondaryFragColor corresponds to an ES2-only concept
(gl_SecondaryFragColorEXT) and does not have any SPIR-V equivalent.

Two fixes were needed:
- sk_SecondaryFragColor shouldn't be in SPIR-V code at all. Report it as
  an error when it appears.
- We don't stop compilation when this error is reported, so we need to
  fix up the assertion that the fuzzer initially discovered.
  Specifically, the fuzzer found that the `sk_SecondaryFragColor`
  variable never got a SPIR-V ID assigned to it in fVariableMap, so the
  compiler would assert when assembling an expression containing that
  variable. Now, we make sure to populate fVariableMap with an (unused)
  ID in `writeGlobalVar` to avoid this crash.

ddc34d96c4 Improved SkSL private type errors
Upcoming dehydration / rehydration changes require $intLiteral and
$floatLiteral to be present in the symbol table (as all other private
types are). It turns out that even with them marked private, having
them in the symbol table allows them to be incorrectly accessed without
error due to a code path that fails to check for private types.

This CL takes care of that and ultimately results in better output from
PrivateTypes.

b920095295 [graphite] Use RAII helper structs to configure append modes in DrawWriter
Move to RAII structs wrapping DrawWriter to control the append mode.
This allows each struct to define any extra template parameters/buffers
needed for the appended data, and expose only the appending API that
makes sense.

In follow up CLs, the RAII structs make it easy to support reserving
and returning vertex data, and add new appending modes.

f4103618ff Report an error if an out param is never written to.
GLSL ES2 behavior is explicitly undefined if an out-param is never
written to: "If a function does not write to an out parameter, the value
of the actual parameter is undefined when the function returns."

We do see divergence here in practice: SkVM's behavior (the parameter is
left alone) differs from my GPU's behavior (the parameter is zeroed
out).

SkSL will now report an error if an out parameter is never assigned-to.
There is no control flow analysis performed, so we will not report
cases where the out parameter is assigned-to on some paths but not
others. (Technically the return-on-all-paths logic could be adapted
for this, but it would be a fair amount of work.)

Structs are currently exempt from the rule because custom mesh
specifications require an `out` parameter for a Varyings struct, even if
your mesh program doesn't need Varyings.

4d1a935835 Avoid error cascades when casting out-of-range scalar values.
Previously, when attempting to cast a huge value to an int, SkSL would
report an error, then return the IR for
`ScalarCast(Int, FloatLiteral(huge-value))` . Now, to minimize the blast
radius of the error, we report the error but return `IntLiteral(0)`.
We've already reported an error, so there's no need to preserve the
value, and zero is less likely to produce follow-up errors.

(A similar approach is used here and worked well: https://osscs.corp.google.com/skia/skia/+/main:src/sksl/ir/SkSLConstructorCompoundCast.cpp;l=57-59)

493a9c0cbc Fix up test SkSLInlineWithInoutArgument.
The test has been moved to shared/, since it's a valid test, but it is
no longer related to inlining, as the inliner no longer attempts to
inline functions with inouts at all.

Also, one function here (outParameterIgnore) actually invoked undefined
behavior and has been removed. According to the GLSL ES2 docs: "If a
function does not write to an out parameter, the value of the actual
parameter is undefined when the function returns." SkVM leaves the value
unchanged, so SKSL_TEST_CPU would pass, but a GPU might clear it (and in
fact, my GPU does).

cc473cd92f Fix fuzzer-discovered error with swizzles.
Some paths through swizzle optimization would replace a swizzles with a
constructor--e.g. `float3(1, 2, 3).y` would be replaced with `float(2)`.
(Constructor::Convert was responsible for replacing this trivial
constructor with the literal `2.0`.)

The optimization code asserted that this replacement would succeed, but
the fuzzer managed to construct a counterexample where the constructor
rejected the value. Specifically, by nesting casts between int3 and
float3, it found a case where Constructor::Convert returned null because
the literal value was out of range for `int` types.

This assertion didn't really add value so removing it was harmless.
Constructor::Convert already reports an error when it fails, and null
returns are handled properly throughout.

3f900d174b Fix issues with SkIsConvexPolygon and SkIsSimplePolygon
The check in SkIsConvexPolygon that determines if a polygon winds around
multiple times turned out to not be correct in all cases. This has been
changed to a much simpler one -- if the sign of the edge vectors change
more than twice, then we know that we've wrapped around more than one
time.

In SkIsSimplePolygon, if both points adjacent to a vertex are on the
right side, we attempt to add both those edges to the active edge list.
However, if they are the same point, then we'll be adding the same edge
twice, which makes the strict ordering of the edge list invalid. Instead
we check for this case earlier on and reject the polygon.
