Change tint's `--fxc` flag to take the path of the FXC compiler DLL.
Have tint attempt to validate with both FXC and DXC if `--validate` is
passed.
Fix the 'dirsWithNoPassExpectations' logic which looks like it got
broken with the tint -> dawn merge. It also incorrectly applied
filepath.FromSlash() on windows.

The structured CFG rule was revised/clarified in SPIR-V 1.6 Rev2
Validation now rejects a few cases.
SpvParserTest, ValueFromBlockNotInBlockOrder
SpvParserFunctionVarTest, EmitStatement_Phi_ValueFromBlockNotInBlockOrderIgnored
SpvParserFunctionVarTest_EmitStatement_Phi_ValueFromBlockNotInBlockOrderIgnored
- Originally from crbug.com/tint/804
Invalid by SPIR-V 1.6 Rev2 update to validation rules:
- Block 80 is a structurally reachable continue target
- Block 25 is not structually reachable, and not part of the loop,
but branches to 80.
vk-gl-cts/graphicsfuzz/cov-dead-branch-func-return-arg/0-opt.*
- The continue construct with the continue target 37[%37]
is not structurally post dominated by the back-edge block 64[%64]
- The SPIRV-Tools inliner no longer creates such cases. It splits the
single-block loop and pushes the continue target down.
vk-gl-cts/graphicsfuzz/nested-for-loops-with-return/0-opt.spvasm
- The loop headed at block 46 does not structurally dominate its merge
block 44. There is a continue-target edge from 41 to 44.

- Continue target 20 also its own loop header, but is not structurally
post-dominated by the backedge block.
- Delete the end-to-end test.
- Keep the unit test because it's about classifying edges, but disable dumping
into the end2end suites.

For error "access violation. Attempted to read from address
0x0000000000000048", added link to GitHub issue I opened. Helps to
understand what these errors are when reading the expectation files.

The OpenGL ES 3.1 spec says:
"The point size is taken from the shader built-in gl_PointSize written by the vertex shader, and clamped to the implementation-dependent point size range. If the value written to gl_PointSize is less than or equal to zero, or if no value is written, the point size is undefined."
ANGLE/D3D11 will emit a warning on this and abort processing, causing dawn_end2end tests to fail.

Implement new transform UnwindDiscardFunctions that replaces discard
statements with setting a module-level bool, adds a check and return for
this bool after every function call that may discard, and finally
invokes a single function that executes a discard from top-level
functions.
Regenerated tests and remove HLSL ones that used to fail FXC because it
had difficulty with discard.

In GLSL, runtime-sized arrays are only valid in interface blocks, not
in structs. The existing code was attempting to avoid emitting structs
containing runtime-sized arrays but was confused by type aliases in
the AST resulting in arrays being missed.
The fix is to do the work on the semantic types instead, where type
aliases have been resolved.

Multiple bugs here:
1) Like texture(), GLSL's textureLod() on depth textures returns a
scalar, and does not need to be swizzled. So set glsl_ret_width to
1 in that case.
2) Like texture(), GLSL's textureLod() always requires a Dref
parameter, so append a zero if not present.
3) GLSL's "lod" parameter to textureLod() is always a float, unlike
WGSL's textureSampleLevel() which is an i32 for depth textures,
so cast it.
Along the way, I discovered that textureLod() is not supported on
samplerCubeShadow or sampler2DArrayShadow (even on Desktop GL). So some
tests will never pass. Logged as https://crbug.com/dawn/1313
