James Price 4d65fc91bb tint: Implement pointer alias analysis
Track reads and writes to pointer parameters for each function in the
Resolver, as well as accesses to module-scope variables. At function
call sites, check the root identifiers of each pointer argument to
determine if problematic aliasing occurs.

The MSL backend passes pointers to sub-objects to functions when
handling workgroup storage variables, which triggers the alias
analysis. Add a validation override for this scenario.

Ben Clayton 75bc93c0df tint: Fix const eval of type conversions
These were quite spectacularly broken.

Also:
* Fix the definition of 'scalar' in `intrinsics.def`. This was in part why conversions were broken, as abstracts were materialized before reaching the converter builtin when they shouldn't have been.
* Implement `ScalarArgsFrom()` helper in `const_eval_test.cc`. This is used by the new conversion tests, and also implements part of the suggestion to improve tint:1709.

dan sinclair 4abf28e29b tint: Add basic support for chromium_experimental_push_constant.
This extension adds support for the push_constant storage class such
that it can be tested with WGSL test files. The real goal is to allow
future transforms that will add push constants that the SPIRV writer
will output.

The extension:

 - Adds the `chromium_experimental_push_constant` enable.
 - Allows the push_constant storage class for global variables.
 - Adds validation that the types are host-shareable for push_constant
   variables, and that they don't contain f16 (must be 32bit types
   only).
 - Validates that at most one push_constant variable is statically used
   per entry-point.
 - Skips validation that the extension has been enabled if
   kIgnoreStorageClass is used.

Tests are added:

 - For parsing of var<push_constant>
   - Caught a missing conversion.
 - For each of the validation rules.
 - For the wrapping of push constants in structs if needed by
   AddSpirvBlockAttribute.
 - For the layout and type rules of the storage class.
 - For a shader with multiple entry-points using various push constants.
    - Caught a missing reset of the previous push constant variable in
      the validation check that at most one is used.
    - Caught the missing wrapping in structs that had to be added to
      AddSpirvBlockAttribute.
    - Caught incorrect logic when adding diagnostics about the call
      graph leading to the reference to push constants.

These were not marked as optional previously because it would mean that
C++ methods would look like void F(a = null, b, c) which is invalid in C++
because default arguments must be contiguous and at the end of the
signature.

This commit adds a special case when optional=true where no_default=true
still marks the argument as optional, but doesn't produce a C++ default
argument.

James Price be656f7984 tint: Implement uniformity analaysis
This implements the uniformity analysis as currently described in the
WGSL specification. Uniformity issues are presented as warnings, and
will be switched to errors in a future release.

A follow-up patch will improve the error messages, which currently
just show the point at which a uniformity was detected.

In a future release, once we have obtained initial feedback from
users, uniformity issues will become errors.

James Price 26ebe5ec36 tint: Refactor if-else statement representation
Instead of using an `if` node that has a list of `else` statements,
make each `if` statement have a single optional `else` statement,
which may itself be an `if` statement (or just a block statement).

This better matches the WGSL grammar (now that we have removed
`elseif`), and simplifies various pieces of code that handle these
statements.

dan sinclair fb5a492787 Fix inclusive language presubmit
The current presubmit has the filter inverted so it would only attempt
to match the filtered files. The file name also has to be converted to
`LocalPath` otherwise it's attempting to compare a python object to a
string and always fails to match.
