    • Vulkan: Split vk::CommandGraphResource. · 193a284d
      Jamie Madill authored 
      This adds two subclasses: RecordableGraphResource and
QueryGraphResource. Each specializes for Buffer/Image/Frambuffer use
cases and Query use cases respectively. No virtual functions are added
to keep best performance.

We also change the CommandGraph API slightly to optimize away the check
for a barrier resource. This requires exposing the set current barrier
API on the CommandGraph.

    • Make perf tests faster in correctness-only mode. · 557a1ee4
      Jamie Madill authored 
      When running with "--one-frame-only" we can also skip the test warmup.
Also we can reduce the internal iteration count to 1 to make the tests
as fast as possible.

    • Run DifferentStencilMasks tests · 9a79c889
      Shahbaz Youssefi authored 
      This test was added and referenced, but was actually never added to the
list of files to be compiled.  The most recent validation work has been
regarding WebGL.

This test verifies the behavior when different stencil masks are set for
front and back faces, which is unsupported in D3D and disallowed in
WebGL.  In the interest of running the test on all back ends, and that
the validation was modified last to improve WebGL support, the test runs
in WebGL compatibility mode.

    • Try to reduce variance in angle_perftests. · 3402d523
      Jamie Madill authored 
      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.
