5af9ce441b tint/resolver: Clean up the resolver built-in unittests
This patch clean up the resolver/builtin_test. The major changes are:
1. Group the testcases by built-in types (array built-ins, logical
built-ins, derivative built-ins, texture built-ins, etc.), and put each
types in a namespace, which may help reading the code.
2. Rewrite the parameterized tests for float and integer built-ins, i.e.
numeric built-in overloads that take at least one float parameter and
all integer parameters. Built-ins that may take either float and integer
parameters, e.g. `abs`, `min` and `clamp`, are tested in both testsuits,
rather than having a third testsuits.
3. Stop checking the detailed candidate lists for float and integer
built-ins in parameterized testsuits.

This patch is helpful for implementing f16 built-ins.

c768e640f4 tint/intrinsics.def: Change language for enums
Previously enum members were added to the global namespace, so that
overload template parameters could be constrained to a single
enum-entry without the need to declare a matcher. While this was a minor
convenience feature, it means that you cannot declare an enum with
members that share the same name as a type. This will be very common for
extensions, like 'f16' where 'f16' is the name of an extension and a
type name.

Change scoping so that enum members need to be fully qualified. Also
change the intrinsic syntax so that enums always need to use a matcher
for enums.

5716611bf0 tint/resolver: Materialize objects when indexed with non-const index
If an abstract-vector or abstract-matrix is indexed with a non-constant index expression, then the resulting value is non-constant, and so cannot be abstract.

In this situation the materialization cannot be done post-index, so materialization must happen on the object before indexing.

aa037ac489 tint: Refactor sem::Constant to be less memory-hungry
Change sem::Constant to be an interface to the constant data. Implement
this so that zero-initialized data doesn't need to allocate the full
size of the type.

This also makes usage a lot cleaner (no more flattened-list of
elements!), and gives us a clear path for supporting constant
structures if/when we want to support them.

3a2a279714 Fixup various warnings in Tint which were accidentally suppressed.
When enabling the SPIR-V reader or SPIR-V writer we were suppressing
-Wnewline-eof, -Wold-style-cast, -Wsign-conversion, and -Wweak-vtables
for the `libtint` cmake target and anything that depended on that
target. Because we'd build all readers/ writers by default this caused
us to never hit those warnings.

A recent change to the cmake build sets the Tint backend based on
the Dawn backend. So, there is a much higher chance of not building
the SPIR-V support if you're on a Mac or Windows machine.

This CL removes the suppression of the warnings, adds specific pragmas
into the SPIR-V reader code which imports the SPIRV-Tools headers
and fixes up the warnings which were then firing due to checking
for the new warnings.

e48ef8ef90 tint/reader: Enable 'const' parsing for unit-tests
This enables the WGSL parsing of 'const' for only tint_unittests,
allowing code to be split up into smaller chunks for review.

Once all the logic is submitted to handle 'const', the test-only
flag will be removed, and 'const' will be enabled for production.
