This change introduces sem::CompoundStatement, a new base class for
statements that can hold other statements.
sem::BlockStatements now derives from sem::CompoundStatement, and
this change introduces the following new CompoundStatements:
* `sem::IfStatement`
* `sem::ElseStatement`
* `sem::ForLoopStatement`
* `sem::LoopStatement`
* `sem::SwitchStatement`.
These new CompoundStatements are now inserted into the semantic
tree as now documented in `docs/compound_statements.md`.
The `sem::BlockStatement::FindFirstParent()` methods have been
moved down to `sem::Statement`.
The `Resolver::BlockScope()` method has been replaced with
`Resolver::Scope()` which now maintains the `current_statement_`,
`current_compound_statement_ ` and `current_block_`. This
simplifies statement nesting.
The most significant change in behavior is that statements now
always have a parent, so calling Block() on the initializer or
continuing of a for-loop statement will now return the
BlockStatement that holds the for-loop. Before this would
return nullptr.

Buffers are padded to be at least 4 bytes. Dawn would
produce invalid barriers for buffers that were "zero"
bytes large. The size for the barrier must be either
non-zero or VK_WHOLE_SIZE. Since we always intend
to transition the entire buffer, simply use
VK_WHOLE_SIZE instead of GetSize() as the size.

When we clear an uninitialized 3D texture, we should clear all depth
slices for each mip level. The current implementation only clears one
slice (the first slice) for each mip level. This change fixes this
bug. Dawn end2end tests of NonzeroTextureCreationTests can pass with
this fix. These tests fail on D3D12 without the fix.
This change also renames arguments for GetRTVDescriptor() for 3D
texture: change baseArrayLayer/layerCount to baseSlice/sliceCount.

Use the new semantic constant value information to significantly reduce the complex indexing logic emitted for UBO accesses.
This will dramatically reduce the number of `for` loops that are decayed to `while` loops.

Move the bulk of the constant evaulation logic out of transform::FoldConstants and into Resolver and sem::Expression.
transform::FoldConstants now replace TypeConstructor nodes that have a constant value on the expression.
This is ground work to:
* Cleaning up the HLSL uniform buffer indexing, which is `/` and `%` arithmatic heavy
* Prepares us to handle `constexpr` when it lands in the spec
* Provide a centralized place to do constant evaluation, instead of the
having similar logic scattered around the codebase.

https://dawn-review.googlesource.com/c/tint/+/56070 introduced maybe_set_synchronized(), which only set synchronized_ when the number of errors reported was less than max_errors_, but it seems the fuzzers have found ways to generate an excessive number of errors that keep the parser synchronized.
Revert 56070, and instead check the synchronized state along with the error count for every unbounded loop in the parser.

This CL removes the old token `Is<Name>()` methods which are no longer
being used in the parser or lexer. (Some of them were used in tests but
the generic `Is(<type>)` is used instead.
New `peek` methods are added which will peek if the given token comes
either next or at the given index.

By generating a helper function for these, we can keep the atomic expression pre-statement-free. This can help prevent for-loops from being transformed into while loops, which can upset FXC.
We can't do the same for workgroup storage atomics, as the InterlockedXXX() methods have the workgroup-storage expression as the first argument, and I'm not aware of any way to make a user-declared parameter be `groupshared`.

The main part of this change is to add a few end2end tests, with
some renaming stuff like arrayLayerCount to sliceCount in order to
include both 2DArray and 3D textures.
The implementation is quite simple: just set UAV descriptor on D3D12.
The new tests can pass on Vulkan and Metal, which indicates the
implementation has been done on them.
The new tests fail on OpenGL and OpenGLES. I will take a look and
submit separate patch for GL and GLES.

Tint now has a single-function API for code generation that
automatically runs the backend-specific sanitizer transforms. This API
allows for backend-specific configuration options such as the fixed
sample mask for MSL (and, in the future, information about which
compiler/version is being targeted), and returns any backend-specific
metadata such as whether a UBO of buffer sizes is required by the
shader.
This change prevents the post-sanitizer program from being exposed to
Dawn, which is a potential foot-gun (e.g. the Inspector is not
expected to be run after the sanitizer transforms, and Dawn is
currently doing this).
The old Generator class API will be removed from Tint shortly after
landing this change.

And remove the u32 overload of frexp (it's not in the spec).
Brings the number of failing tint end to end tests for MSL down to 19/1098.
The WG still haven't found consensus on reworking these two intrinsics.
It's very likely that their signature will change so that they return a structure instead of returning a value and outputing another as a pointer.
Until the WG makes a decision, let's implement these according to the current spec.
Some overloads are still failing due to MSL missing overloads of the pointer parameter being in the `threadgroup` address space.
I'm holding off fixing these until we know what's happening with these intrinsics.

Adds a new single-function API for the generators, which applies the
sanitizing transform and performs the generation in one step, and
returns a result object which contains the generated code and success
status/diagnostics.
The new APIs take an `Option` structure to control backend-specific
generation details (e.g. MSL fixed sample mask). The result objects
also provide backend-specific feedback (e.g. whether a UBO of buffer
lengths was generated).
HLSL needs a list of entry points to validate, and it's the HLSL
sanitizer that generates an entry point for programs that do not have
one. This change makes the HLSL generator return the list of
post-sanitize entry points so that the Tint executable can forward
them to the validation code.
