This option is used to initialize shared variables to zero at the
beginning of shader execution to avoid compute shaders being able to
read undefined values that could be coming from another webpage or
application.
It's implemented by declaring variables with initial value for HLSL.
For GLSL, it's not allowed to use declaraction initializer for shared
variables, so we need to explicitly assign them to zero at the
beginning of main(). This implementation is only for HLSL.

This switches from using resource barriers for buffers to using global
barriers. This matches the general advised best practice. It also
allows us to combine multiple barriers into one. On a draw we might
combine all the vertex and index barriers into a single barrier call.

We implement this using a bit of extra state tracking in BufferHelper.

These tests make sure that a depth- or stencil-only format that is
emulated with a depth/stencil one does not affect clear/draw in such a
way that it would expose the hidden aspect.

By nature of the emulation, it's not trivial to read back the hidden
aspect.  This test simply makes sure the hidden aspect doesn't affect
rendering, but is not a definitive test of correctness.

S8_UINT and D24_UNORM_X8_UINT are the only formats currently that are
single-aspect and are possibly emulated with a packed depth-stencil
format if it's not supported.  A flag to FeaturesVk has been added as a
way to force this behavior for the sake of testing.

This test is added to ensure the correct clear algorithm is used for
this case.  Additionally, this case is detected and the other aspect is
forcefully cleared to 0 whenever the original aspect is cleared.

This test verifies the behavior when different stencil masks are set for

the validation was modified last to improve WebGL support, the test runs

This change does a few things:

- make perf test runner script print % variation instead of stddev

This makes it a bit more clear how much variance there is.

- stabilize CPU in the render perf tests

Setting a thread affinity and priority should stop from switching cores
during the run. Hopefully can prevent background noise from changing
the test results.

- warm up the benchmark with a few iterations

This should hopefully make the test results a bit more stable.

- output a new normalized perf result value

The new result is normalized against the number of iterations. So it
should hopefully be stable even if the number of iterations is changed.

- increases the iteration count in the draw call perf tests.

These tests were completely dominated by SwapBuffers time. Increasing
the iterations per step means we actually are bottlenecked on CPU time
instead.
