There are a few places that will remain std::unordered_map due to build
or run-time errors, which will need to be evaluated more closely to
determine if they should remain std::unordered_map or if there is
another Abseil data structure that would be more efficient while still
working correctly.

When the render pass breaks while transform feedback is active, the
subsequent render passes didn't restart transform feedback because of a

In order to be able to land SwANGLE in Chromium, this cl adds
suppressions for memory leaks detected by LSAN. Some of these should
be fixed and some are intentional leaks of global variables.

This cl should allow the linux_chromium_asan_rel_ng bot to pass while
using SwANGLE and shouldn't break the win-libfuzzer-asan-rel bot.

Some apps (possibly those that use Skia) use the extension
GL_CHROMIUM_bind_uniform_location, which is implemented by ANGLE. This
leads to traces that contain calls to functions from this extension,
such as: glBindUniformLocationCHROMIUM. Such traces do not replay on
native GLES drivers, as the extension is not available.

The fix is to disable the GL_CHROMIUM_bind_uniform_location extension
when capturing, so that apps do not use this extension.

Enables OES/EXT_shader_io_blocks extensions in Vulkan backends.

With shader I/O blocks, the varyings can now be an array of struct (the
block itself) of struct (nested in the block).

This change is missing a number of features.  In particular, if the
shader I/O block has a location decoration in the middle of the block,
that is not handled yet.

Based on changes from m.maiya@samsung.com and jmadill@chromium.org.

This reverts commit 0f083ab0.

Reason for revert: Seems to be blocking the ANGLE auto-roller (see: http://anglebug.com/5422)

As ANGLE doesn't redeclare gl_PerVertex, glslang always defines it with:

    gl_Position
    gl_PointSize
    gl_ClipDistance
    gl_CullDistance

The unused members here contribute to varying component limits.  The
last two are unlikely to be used, and the second member is rarely used
as well.

This change keeps it simple and strips the trailing inactive members,
which for all intents and purposes accurately minimizes this struct.

When a test mark as flaky fails consistently we need to avoid marking
the test as flaky. We treat is as a deterministic failure. This means
we output "PASS" as the expected result instead of "PASS FAIL". That
change will produce the correct behaviour with the test scripts.

Also adds missing test runner output when we retry a flaky test.
