Austin Eng 3890934033 fuzzing: Create Instance and discover Adapters only once
This patch moves Instance initialization and adapter discovery so that
it is done once globally, and not for every fuzz input. This is to work
around a bug where destructing the instance at the end of a run breaks
when fuzzing with Swiftshader.

Austin Eng 470921fe46 Reland "fuzzing: Add supportsErrorInjection option to DawnWireServerFuzzer"
This is a reland of f58f69f66b

The whitebox dawn_end2end_tests are updated to link statically against
libdawn_native. This is required because the test link against and use
libdawn_native as sources. It is an error with MSVC to both import and
export symbols from libdawn_native.

Austin Eng 87d3138158 Revert "fuzzing: Add supportsErrorInjection option to DawnWireServerFuzzer"
This reverts commit f58f69f66b.

Reason for revert: This breaks the MSVC build because the whitebox end2end tests try to both import and export the error injector symbols from libdawn_native

Ryan Harrison be5c135672 Refactor code to have rudimentary support for using SPVC
This is the first step for having a fully operational SPVC usage
path. This version of SPVC integration uses SPVC for setting up the
options to the compiler, but a lot of the actual interaction with
spirv-cross is done in Dawn, just via SPVC's compiler object.

Future CLs will migrate more of the spirv-cross interaction to using
the SPVC API, eventually removing the need for Dawn to know about
spirv-cross.

Corentin Wallez 96496828a0 Split the libdawn target in components with a single purpose.
The functionality of the dawn_headers and libdawn targets are split into
the following targets:

 - dawn_headers: the new version only exposes the "dawn.h" C API and no
   longer includes the C++ API.
 - dawncpp: the header and implementation of the C++ API that wraps the
   C API. This is unbundled from the rest so the C++ API can be used
   with libdawn_proc or other libraries implementing the C API.
 - libdawn_proc: A DawnProcTable-backend implementation of the C API.

This is needed because in follow-up commit there will be three libraries
implementing the C API: libdawn_proc that trampolines where we want, and
libdawn_native/wire that don't have trampolines for better perf.

uses it to implement data transfers for buffer mapping.

This patch also provides a default "inline" implementation of

Because implementations of MemoryTransfer perform their own
serialization, a skip_serialize option is added to WireCmd records.

Jiawei Shao 5490e9aca1 Fix clip space on D3D12 and OpenGL
The range of the Z-coordinate in clipping volume is [-w, w] on OpenGL,
while it is [0, w] on D3D12, Metal and Vulkan.

In this patch, the "fixup_clipspace" flag of SPIRV-Cross is enabled on
OpenGL backend and disabled on D3D12 backend to unify the behaviour of
clip space on all Dawn backends. An end2end test is also added for this
fix.

This patch also fix a bug when clearing depth stencil attachments on
OpenGL backend. Before clearing depth stencil attachments, we should
enable depth stencil writing by properly setting depth and stencil
masks. We do not need to set the depth and stencil masks back because
they will be set again when applying the render pipeline. The newly
added test will fail without this fix when running the test together
with all the end2ends.

Corentin Wallez bd48385d50 Add static library versions of libdawn*
Chromium will want to have both static and shared library versions of
Dawn to use in non-component and component builds respectively.

The *_export.h files are modified to noop when *_SHARED_LIBRARY is not
defined so that the static library doesn't export symbols that aren't
imported in dependents (this would break compilation on Windows).

A dawn_library_combo is introduced in BUILD.gn that factors out all the
logic needed to produce shared libraries and handle the _EXPORT macros.

Also contains a fix to dawncpp to export only the methods that aren't
defined in the header (otherwise they get defined multiple times)

SetImplementation takes a pointer and would be shimmed by browsers so we
skip the call in the fuzzer, otherwise we'd dereference arbitrary

Ryan Harrison fbeca676d4 Tighten when signal trap is used in SPIRV-Cross fuzzers
Due the jump within the signal trap used in these fuzzers, local scope
allocations cannot occur while the signal trap is on, otherwise there
is a possibility of leaks. This CL rewrites how the code under test is
run, so that the potentially aborting code is tightly wrapped by
signal trap without any local scope allocations.

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.
