Ben Clayton 51be3420b8 tint/writer/glsl: Fix emission of lowest i32 value
GLSL has the same behavior as MSL, in that -2147483648 is parsed as
a unary minus on '2147483648'. 2147483648 overflows an i32, so this
actually gets treated as -0.

Ben Clayton 03de0e83ae Move tint::transform::Robustness to a santizier transform
There's no good reason for this to be public.
Move it into the writers, and expose a 'disable_robustness' option to
turn it off. This can be expanded to hold more fine-grain control in the
future.

Zhaoming Jiang 7d7976d590 tint: Add end-to-end tests for expressions using f16 types
This patch add DXC compile flag "-enable-16bit-types" and change profile
to SM6.2 when validating generated HLSL using DXC if f16 extension is
enabled in the WGSL program.
The patch add Tint end-to-end test cases for expressions using f16 type,
including constructor, binary operator, splat, zero-init, and others.
Testcases that use f16 types in uniform or storage buffer are SKIPped,
because such usage is not implemented yet.

Ben Clayton 7d34de88f1 tint/test-runner: Split expectations for FXC and DXC
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.

By refactoring these methods, they're easier to read, and contain less
