199440e37c tint/ast: Change StructMember::symbol to StructMember::name
StructMember::name is an ast::Identifier.

The goal here is to have all AST nodes use an identifier instead of
symbols directly. This will greatly simplify the renamer transform,
and gives the symbol a Source location, which is helpful for
diagnostics and tooling.

01ac21cc9a tint: Rename ProgramBuilder::Construct() to Call()
Once all ast::Type derived classes are removed, there will be no
distinction between a type initializer / conversion and a function call.

18b2158b4e Move ast/address_space to type/
This CL moves the ast/address_space to type/address_space. This breaks
the type dependency on ast for AddressSpace.

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.

6e77b47ed9 Update internals to initializer instead of constructor.
This CL catches up the internals (along with a few error messages) to
say `initializer` instead of `constructor.

98a7cd11af Add a ClampFragDepth transform.
Add clamping of the @builtin(frag_depth) output of fragment shaders using
two push constantsprovided by the outside environment. For example the
following code:

  @fragment fn main() -> @builtin(frag_depth) f32 {
      return 0.0;
  }

Is transformed to:

  enable chromium_experimental_push_constant;

  struct FragDepthClampArgs {
    min : f32,
    max : f32,
  }

  var<push_constant> frag_depth_clamp_args : FragDepthClampArgs;

  fn clamp_frag_depth(v : f32) -> f32 {
    return clamp(v, frag_depth_clamp_args.min, frag_depth_clamp_args.max);
  }

  @fragment
  fn main() -> @builtin(frag_depth) f32 {
    return clamp_frag_depth(0.0);
  }

Fixed: tint:1620
