686ccec13f [graphite] Add BackendTexture abstraction for Graphite.
There are definitely some missing getters on other functions we'll need
on BackendTexture. But for this CL I just wanted to get the basics and
ctor working. Other functions can be added as they are needed.

14a487fd54 Replace getConstantSubexpression with getConstantValue.
The only type of expressions that getConstantSubexpression could ever
return are Literal and nullptr. getConstantValue now returns an
optional<double>; nullopt indicates a non-constant value in the slot.
This simplifies most use cases, and allows us to get rid of some extra
"zero" and "one" Literal objects in some of our Constructor classes.

This change fixes a recent fuzzer issue. The fuzzer had discovered that
calling `getConstantSubexpression` on a ConstructorCompoundCast that
contained a compile-time-constant value would return literals of the
wrong type (the cast was not applied). By nesting repeated matrix casts,
this type confusion could be turned into an assertion.

c0ff5a8560 Add flag that can be used to disable std::shared_mutex use in VMA.
This is needed for enabling Skia's Vulkan backend for Flutter on Windows and iOS 9, as the standard libraries in both of these contexts don't have `std::shared_mutex`.

When disabled on Windows, VMA falls back to using Win32 SRWLock.
The `vulkan.h` import in `vk_mem_alloc.h` which would normally import `windows.h` is commented out for Skia, and so the relevant symbols need to be declared before importing `vk_mem_alloc.h`.

We should support constant-expressions involving matrices (GLSL ES2
does, WebGL does). We currently don't. We do properly report out-of-
range indexing, but we don't optimize away valid matrix index
expressions or allow matrices to be indexed in a constant-expression
context.

0b84159e3b Improve array-indexing tests.
Previously, we didn't have tests which leveraged constant-evaluation of
array indexing (because we didn't support it), and our test files
commingled constant-indexing into vectors with constant-indexing into
arrays.

The test files now separate vector- and array-handling into separate
tests, and a ton of new cases have been added to ArrayFolding. The
ArrayFolding tests now require constant-evaluation of array indexing,
so they fail in this CL, but will be fixed in the followup CL.

6e6ae1b762 Fix inlined out-of-range vector access.
Previously, this code assumed that IndexExpression::Convert had done
range checking and that it was safe to access the base expression at
the passed-in index. The inliner violates this assumption, because it
can replace unknowns (where out-of-range access is undefined but non-
fatal) with knowns (where out-of-range access is forbidden).

We now do range-checking inside IndexExpression::Make and report the
error cleanly, instead of asserting inside of Swizzle::Make due to an
invalid component index.

ee525493ea Add test for incomplete expressions.
The ExpressionStatement currently eliminates dangling references without
reporting them as an error. This happens due to optimization; these
expressions (being meaningless) have no side effects, and so the
optimizer replaces them with Nop. When the optimizer is off, these
programs trigger an assert:

e7a9535247 Enforce basic limits on global size in SkSL.
Much like http://review.skia.org/467759, this CL defensively guards
against programs which consume more space than is reasonable. Globals
exist outside of functions, so they wouldn't be caught by the stack size
checks.

7cde28909f Enforce basic limits on function stack size in SkSL.
Functions that declare variables totaling more than 100,000 slots will
now generate an error.

This is only a partial mitigation to the problem, as a sophisticated
attack could still chain/nest multiple functions together to consume
extremely large amounts of stack. However, this mitigation is still more
sophisticated than our peers; both WebGL and glslang are susceptible to
similar problems, and in the general case (ES3+ with full flow control)
it's intractable.

390edeb88d Fix fuzzer-discovered error with no-op arithmetic.
The fuzzer triggered this error in a strange way that involves parsing a
TK_INVALID token. The fuzzer's original input used \xFF bytes in the
shader text to do this. I replaced these with the ` character since it
behaved the same, but allows our test inputs to remain basic ASCII.

The root problem is that `cast_expression`, part of no-op arithmetic
simplification, can now fail because expressions like `int(4000000000)`
no longer get past Constructor::Convert. Previously we had assumed
`cast_expression` could never return null; now we check its result for
null before using it.

aa369d2b8e Fix error with inlined literals overflowing their types.
It's possible to write code containing errors that are only apparent
once the inliner runs. For instance, a function which takes a short and
returns its negative it is valid for most inputs, but undefined for
-32768 (because +32768 does not fit in a short). A function which takes
floats and casts them to ints is valid for many inputs, but not valid if
you pass in 5 billion.

This CL restructures our out-of-range integer error detection to report
errors cleanly in these cases instead of asserting. It also refactors
the range checking code to be usable in situations where we don't yet
have a Literal expression.

Reason for revert: need to revert parent CL

>
> We need recursive chopping/culling logic in order to draw
> astronomically large paths. But rather than do that at the same time

ef8907c69f [graphite] Rename UniformDataManager to UniformManager and update
Gerrit didn't do so well on this CL. What's changed in the UniformManager is:

a lot of unused stuff was pared out of the UniformDataManager
the Write methods now return the number of bytes written in the call (incl. padding)
all the "#ifdef SK_DEBUG" stuff is new to validate against the prior way of writing uniforms

b34e97b5d9 Add Android HWAddress Sanitizer tasks.
Design doc: http://go/skia-android-hwasan.

This CL defines the following tasks:

- Build-Debian10-Clang-arm64-Debug-Android_HWASAN
- Test-Android-Clang-Pixel4a-CPU-Snapdragon730G-arm64-Debug-All-Android_HWASAN
- Test-Android-Clang-Pixel4a-GPU-Adreno618-arm64-Debug-All-Android_HWASAN

The HWAddress Sanitizer is only available on 64-bit Arm devices, and requires Android 10+ built with HWAddress Sanitizer support. There are prebuilt HWASan images for supported Pixel devices at https://ci.android.com (instructions at https://developer.android.com/ndk/guides/hwasan).

To support these tasks, we added two Pixel 4a devices to the tree, flashed with the corresponding prebuilt HWASan image. The specific Pixel devices were chosen based on stock availability.

See patchset 11 for an example error I introduced in //gm/3d.cpp, which was caught by the HWAddress Sanitizer.

ab0a13d9d9 Removed the final remnants of IRGenerator
This completes the long process of moving all of IRGenerator's code and
data into better homes and finally kills the class altogether. There is
a lot of #include churn here due to poor header hygiene in the past;
IRGenerator.h included a ton of stuff and almost everything included
IRGenerator, allowing us to inadvertently be sloppy with our includes.
