7bca4d7293 tint: Remove constant::Value::AllEqual()
The only uses of this method were to check for splats when emitting
vector constants in some backends, and they can just check for
constant::Splat instead.

574b4b1996 tint: Fix constant::Splat conversion of struct types
Conversion can happen for structure materialization (modf, frexp).
If both structure members are the same type and value, then a constant::Splat will be constructed, which needs to handle conversion.

6cc183c85a Generic template and forward in stringstream.
This CL updates the templates in the StringStream to match more types.
All of the internal `operator<<` methods have been converted over to
StringStream. The precision was increased in order to better match the
precision needed to read back as a double.

971318f7a2 tint: Replace all remaining AST types with ast::Type
This CL removes the following AST nodes:
* ast::Array
* ast::Atomic
* ast::Matrix
* ast::MultisampledTexture
* ast::Pointer
* ast::SampledTexture
* ast::Texture
* ast::TypeName
* ast::Vector

ast::Type, which used to be the base class for all AST types, is now a
thin wrapper around ast::IdentifierExpression. All types are now
referred to using their type name.

The resolver now handles type resolution and validation of the types
listed above based on the TemplateIdentifier arguments.

Other changes:
* ProgramBuilder has undergone substantial refactoring.
* ProgramBuilder helpers for type inferencing is now more explicit.
  Instead of passing 'nullptr', a new 'Infer' template argument is
  passed.
* ast::CheckIdentifier() is used for more tests that check identifiers,
  including types.

5addefb148 Rename Constant::As to Constant::ValueAs.
This CL updates Constant::As to be Constant::ValueAs. Now that Constant
inherits from CastableBase, there is already an As method on
CastableBase. This makes the override inside Constant confusing and
potentially incorrect.

d4908670e1 tint: clean up const eval test framework
- Remove Types variant, and replace with a type-erasing Value class
  instead. This is not only better for compile times, but makes the code
  much easier to understand.
- Value wraps an internal shared_ptr to a const detail::ValueBase,
  allowing it to be used as a value-type (i.e. copyable), while behaving
  polymorphically.
- Add static_asserts to Val, Vec, and Mat creation helpers to emit a
  more useful error message when the wrong type is passed in.

29fb8f8eef tint: optimize compile time for const_eval_*_test files
The reason for slow compile times is because the very large variants of
builder::Value<T>s combined with the many std::visits over these
variants result in many combinatorial instantiations of the visit
callbacks.

To address this, I added a polymorphic base class ValueBase to Value<T>,
and replaced most of the std::visit-based compile time code with runtime
virtual calls. For the two heaviest users of std::visit over the large
variants, compiles times dropped more than half (clang-10, debug):

const_eval_binary_op_test.cc: 19.079s to 7.736s
const_eval_unary_op_test.cc: 10.021s to 4.789s
