This change adds a comment related to the use of host_toolchain to
account for cross compilation, and removes a print statement that had
been accidentally left in a build script.

Ben Clayton 6e459fecb7 sem: Add CompoundStatement
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.

Ben Clayton 71f619b6f1 [resolver]: Begin constant value evaluation
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.

Ben Clayton 03c8393213 [writer/msl]: Implement modf and frexp
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.

Ben Clayton e4fd4a2ecd test/intrinsics/gen: Use '0' for level parameters
The level parameter needs to be zero for a number of texture overloads.
Bodging the template to emit 0 instead of 1 for any `level : i32` parameter is the easiest fix here.

James Price af89c729ed writer: Move sanitizers into the backends
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.
