6d5542d703 Fix compilation error in delete_statement.cc
There seems to have been a race between changes and
SwitchStatement::body is no longer an std::vector but a utils::Vector.

1884c964d7 tint: Fix utils::Vector<T, 0>::Push segfaulting
Grow multiplies capacity by 2, but for a 0-sized Vector (i.e. no small
array), capacity is 0, so Grow wouldn't grow.

This patch implement modf and frexp built-ins for f16 types, and also
simplify their implementation for f32 in MSL and HLSL, and clean up
deprecated code in GLSL writer. Corresponding unittests are also
implemented, but end-to-end tests for f16 are not implemented yet.

7d8307122e Cleanup some strings; Reorder attribute rule.
This CL inlines some strings which were listed at the top of the
parser. In general, we've inlined the strings there were just a few
which ended up being declared at the top of file.

The `attribute` rule is re-ordered to sort the attributes in
alphabetical order so they're easier to locate.

The `expect_storage_class` rule is renamed `expect_address_space`

737fd8223e Add expression into the WGSL parser.
The parser skipped over the `expression` node and went straight
to `logical_or_expression`. This CL adds `expression` which just
calls `logical_or_expression`. This will allow moving the rest of the
parser to more closely match the WGSL spec.

Testcases that use f16 types in uniform or storage buffer are SKIPped,

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.

4a65620716 tint/resolver: Handle array() constructors
If the array constructor has no explicit type and count, infer from the
arguments.
Implement and test array materialization.

Also:
* Change sem::AbstractNumeric::IsConstructable() to return true. This
  has changed in the WGSL spec.
* Fix the test-helper builder for DataType<array<N, T>> - it was
  incorrectly calculating the array size.

239a92d2d0 tint: transform::RemovePhonies: skip builtins with no side effects
This transform was attempting to remove builtins with no side
effects, such as a call with abstract int/float args, which is unhandled
by this transform. For example, this would cause the transform to ICE:

_ = clamp(1, 2, 3);

Fixes ClusterFuzz issue crbug.com/1348739.

bf32bd4e96 tint/ast: Tighten AST definition of runtime-sized array
Just checking whether the count is nullptr is not sufficient to know
whether the array is fixed-size:

`array` represents a infered type, infered fixed-size array
`array<T>` represents an explicit type, runtime-sized array
`array<T, N>` represents an explicit type, explicit fixed-size array

Also excludes certain common keywords from the set of identifiers that

* frexp
* modf

The end-to-end tests for f16 built-in are not added yet.
