c6b381495d tint/transform: Refactor transforms
Replace the ShouldRun() method with Apply() which will do the
transformation if it needs to be done, otherwise returns
'SkipTransform'.

This reduces a bunch of duplicated scanning between the old ShouldRun()
and Transform().

This change also adjusts code style to make the transforms more
consistent.

This CL catches up the internals (along with a few error messages) to
say `initializer` instead of `constructor.

f7e2de7971 tint: make RemovePhonies remove call statements to builtins that return a constant value
If the return value of a builtin is a constant value, it may be an
abstract number, and our backends currently do not deal with abstract
numbers. As these builtins have no side-effects, and the return value is
unused, we can just drop the call altogether.

This is needed for the follow-up CL that fixes calls to builtins with
abstract args of different type.

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.

e5a67ac891 tint: Remove ast::CallExpression -> sem::Call implicit mapping
With abstract materialization, any ast::Expression may map to the new
sem::Materialize node. Because of this, we can't assume that an
ast::CallExpression maps to a sem::Call, as it might be wrapped by a
sem::Materialize.

Remove the mapping, and fix up all the code that was relying on this.

Fixes are done by either:
• Calling `UnwrapMaterialize()->As<sem::Call>()` on the semantic
  expression. This is done when the logic may assume it's possible for
  the expression to be a Materialize node.
• Using the explicit sem::Info::Get<sem::Call>() template argument to
  cast the semantic type to sem::Call. This is done when the logic
  either knows it is impossible for the expression to be a Materialize.

The backends have been stubbed, as we'll want to emit the constant value
for these nodes. It's likely that we'll just use the FoldConstants
transform to strip all Materialize nodes from the tree. For now, be
defensive.
