Ben Clayton bf39c8fb19 sem: Replace SwitchCaseBlockStatement with CaseStatement
The SwitchCaseBlockStatement was bound to the BlockStatement of an ast::CaseStatement, but we had nothing that mapped to the actual ast::CaseStatement.
sem::CaseStatement replaces sem::SwitchCaseBlockStatement, and has a Block() accessor, providing a superset of the old behavior.

With this, we can now easily validate the `fallthrough` rules directly, instead of scanning the switch case. This keeps the validation more tigtly coupled to the ast / sem nodes.

Ben Clayton 177e7bfa5d IntrinsicTable: remove double underscores
'__' is reserved in C++, and the 'match__' and 'build__' functions are causing OSS-fuzz builds to fail.

Add the change in tint behavior to the OT notes.

Add end to end tests for underscores. While the GLSL and MSL compilers seem to accept leading and double underscores in identifiers, the tint build failure has highlighted we have more work to do here (crbug.com/tint/1319)

Ben Clayton 4183051b54 resolver: Add dependency-graph analysis
Performs a module-scope (global) declaration dependency analysis, so
that out-of-order global declarations can be re-ordered into dependency
order for consumption by the resolver.

The WGSL working group are currently debating whether out-of-order
declarations should be included in WebGPU V1, so this implementation
currently errors if module-scope declarations are declared out-of-order,
and the resolver does not currently use this sorted global list.

The analysis does however provide significantly better error diagnostics
when cyclic dependencies are formed, and when globals are declared
out-of-order.

The DependencyGraph also correctly now detects symbol collisions between
functions and types (tint:1308).

With this change, validation is duplicated between the DependencyGraph
and the Resolver. The now-unreachable validation will be removed from
the Resolver with a followup change.

Vulkan requires round-to-nearest when converting from a float
coordinate to an integer array layer. It prefers round-to-nearest-even.
Use round-to-nearest-even, instad of relying on the rounding behaviour
of the i32(f32) overload.

Stephen White 0ff3050c6c GLSL: a grab bag of texture fixes.
Use imageSize() on images, not textureSize().
In GLSL, the LOD parameter to textureSize() is mandatory for
sampled textures, so emit a default 0 if not supplied. (Also, don't pack
the level into the coords argument; that's an HLSLism.)
GLSL returns the array size of array textures in the final component
of textureSize(); remove it for WGSL.
Write the subtype of storage images correctly (uimage*, iimage*, etc).
This required a bit of cleanup to move "writeonly" ahead of subtype
emission.

Austin Eng 38fa643702 Add HLSL/MSL generator options for ArrayLengthFromUniform
ArrayLengthFromUniform is needed for correct bounds checks on
dynamic storage buffers on D3D12. The intrinsic GetDimensions does
not return the actual size of the buffer binding.

ArrayLengthFromUniform is updated to output the indices of the
uniform buffer that are statically used. This allows Dawn to minimize
the amount of data needed to upload into the uniform buffer.
These output indices are returned on the HLSL/MSL generator result.

ArrayLengthFromUniform is also updated to allow only some of the
arrayLength calls to be replaced with uniform buffer loads. For HLSL
output, the remaining arrayLength computations will continue to use
GetDimensions(). For MSL, it is invalid to not specify an index into
the uniform buffer for all storage buffers.

After Dawn is updated to use the array_length_from_uniform option in the
Metal backend, the buffer_size_ubo_index member for MSL output may be
removed.

Antonio Maiorano 11d09f2fe7 HLSL: force FXC to never unroll loops
Emit the "[loop]" attribute on "for" and "while" so that FXC does not
attempt to unroll them. This is to work around an FXC bug where it fails
to unroll loops with gradient operations.

FXC ostensibly unrolls such loops because gradient operations require
uniform control flow, and loops that have varying iterations may
possibly not be uniform. Tint will eventually validate that control flow
is indeed uniform, so forcing FXC to avoid unrolling in these cases
should be fine.
