Ryan Harrison 9854295ff6 Add fuzzers for SPIRV-Cross
This CL adds in fuzzers for SPIRV-Cross for HLSL, GLSL, and MSL
outputs. These fuzzers live in Dawn because there is not appropriate
location in the Chromium source repo for them and it is unlikely they
would be land-able in the SPIRV-Cross repo, because it is not coupled
with Chromium's build system and thus Clusterfuzz so would be
effectively dead code. Dawn depends on this code, but it is also
integrated into the Chromium build system, so this was the best place
I could find for them

The code under fuzz unfortunately uses exceptions/aborting as its
error reporting mechanism. This is an acknowledge short coming and
there are efforts to remove this behaviour. To work around this and
reduce the number of false positives found by the fuzzers, a signal
trap has been implemented which will be removed once the code under
fuzz has been updated.

The trap replaces the existing signal handler and silencing signals
while running the code under test. This allows the code under test to
call abort() and not crash the fuzzing process. Theoretically, only
SIGABRT should need to be trapped, but something is causing the signal
from abort() to be converted to SIGSEGV when running under ASAN.

This signal trap has been tested with the fuzzing/sanitizers by
intentionally inserting bad calls that will occur after a few thousand
test cases. It was confirmed that the fuzzer detected the issue and
stops fuzzing.

The alternate to implementing this signal trap would be to turn on
exceptions for the fuzzer. This was attempted, but proved to be
fruitless due to what was reported as an ODR issue, but couldn't
couldn't be silenced. The likely underlying issue was a pre-built
library or other object being built without exceptions was causing
different versions of symbols or the exception version of the standard
library not being instrumented by ASAN. Given the majority of Chromium
eco-system turns off exceptions, fixing this issue would not be
helpful to the larger community and was looking like it would require
significant effort.

Corentin Wallez e92ad5bb89 Build with a different gtest harness when in Chromium
Running test in a Chromium build requires using their gtest and gmock
targets as well as a harness that is in //base. Since we want to run
Dawn tests on the Chromium GPU bots, we need to support two
configurations both building tests standalone and in Chromium.

Corentin Wallez 16092faa16 Roll shaderc and glslang and use their BUILD.gn
This rolls glslang and shaderc to be able to use their BUILD.gn files,
and also rolls SPIRV-Tools and spirv-headers to have compatible
versions.

Corentin Wallez ec72443bf1 GN: Fix MSVC compilation
third_party/BUILD.gn was adding compile flags to suppress failures that
were GCC/Clang specific and caused MSVC to error out. Replace them by
suppression using MSVC's flags.

Corentin Wallez 5b61abce09 Fix Windows compilation using GN and clang-cl.
This includes a bunch of fixes for clang warnings in Windows specific
code that was only compiled by MSVC previously. This also tidies up some
BUILD.gn issues on Windows.

Corentin Wallez d2969a7d3d Make Dawn "gn check" by default (except SPIRV-Tools)
This required adding some missing dependencies, splitting public headers
of libdawn_[native|wire] so they aren't hidden in the
libdawn_[native|wire]_sources targets, and making unittests depend on
sources directly instead of static libraries (which is almost equivalent).

As a byproduct, Empty.cpp is no longer needed and is removed.
