95586ff184 Add Log.h to replace all uses of iostream
On Android iostream doesn't appear in logcat, the system log that's
often used for printf debugging. Introduce Chromium/ANGLE like logging
that looks like the following:

  InfoLog() << stuff << stuff;

This makes sure the message is put in logcat on Android and removes
static initializers from <iostream>

4b0b7a532a Skip validation during command recording when skip_validation is on
This patch factors resource usage tracking so it is separate from
command validation, allowing the bulk of command validation to be
completely skipped.

In DrawCallPerfRun/Vulkan_DynamicPipeline_DynamicBindGroup, disabling
validation cuts roughly 74 nanoseconds (20%) of CPU time, per draw.

In DrawCallPerfRun/Vulkan_DynamicBindGroup, disabling validation
cuts roughly 35 nanoseconds (17%) of CPU time, per draw.

In DrawCallPerfRun/Vulkan_MultipleBindGroups, disabling validation
cuts roughly 45 nanoseconds (14%) of CPU time, per draw.

cfc9c6e322 Make perf test tracing thread-safe
The Metal driver calls command buffer completion callbacks on a
separate thread so enqueueing these trace events needs to be made
thread-safe. In the future, Dawn will probably have other threads
that also require thread-safe tracing.

In this CL, each thread records trace events into its own buffer,
and all buffers concatenated when trace events are acquired.

64a3bb93dc Add DrawCallPerf tests
These tests draw a simple triangle with many ways of encoding commands,
binding, and uploading data to the GPU. This tests the performance of Dawn's
validation, command recording, and submission by switching buffer
bindings, bind groups, and pipelines. Some test instantiations upload
per-draw data to test efficiency of resource transitions or pre-record
commands in a render bundle.

7a7d547381 perf_tests: Always capture trace events and flush incrementally
Previously, the trace event buffer was cleared after *all* tests
completed. In order to avoid allocating a ton of space to hold
traces, this patch factors the trace event recording so that the
buffer is processed and reset at the end of each test trial.

This patch also prepares for the future where trace events will be
processed at the end of each trial to compute additional metrics.

31bde95857 perf_tests: Replace WaitForGPU with maxStepsInFlight argument
The current BufferUpload perf test calls WaitForGPU at the end of
every step to time how long the batch of uploads took. Future tests
will want to have multiple Steps or Frames in flight to mimic real
applications that use double or triple buffering. This patch removes
WaitForGPU and adds a |maxStepsInFlight| argument which a test can
set to configure how many steps can be running on the GPU.
For the BufferUpload tests, this is still 1.

Because perf tests are parameterized to support multiple test
variants, this patch also adds DawnTestWithParams and ParamGenerator
