The resolver now wraps sem::Expression objects with a sem::Load object
anywhere that the load rule is invoked. sem::Expression provides an
`UnwrapLoad()` method that returns the inner expression (or
passthrough, if no load is present), which is analaguous to
Type::UnwrapRef().
The logic for alias analysis in `RegisterLoadIfNeeded` has been folded
into the new `Resolver::Load` method.
Fixed up many transforms and tests. The only difference in output is
for a single SPIR-V backend test, where some IDs have changed due to
slight re-ordering of when expressions are generated.
There may be further clean-ups possible (e.g. removing unnecessary
calls to `UnwrapRef`, and simplifying places in the SPIR-V writer or
transforms that deal with memory accesses), but these can be addressed
in future patches.

Don't use dynamic casting in hashing and equality. These should be fast, and dynamic casting is expensive.
Add type::UniqueNode for things that need de-duplicating and bin the types on construction.
Replace some use of SFINAE with constexpr.
Also fixes a build failure for x86.

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.

This Cl splits the concrete constant implementations out of the
const_eval.cc file and into individual files. The classes are left in
the resolver namespace and will have a namespace update in a followup
CL.

It was not considering structures, and the default clause was happily assuming two std::monostates (no-value) were equal.
This lead to non-deterministic behaviour as the Hash() would sometimes match and sometimes not.

This CL implement f16 for pipeline IO, i.e. vertex shader input,
interstage variables between vertex and fragment shader, and fragment
shader output (render target). Unit tests and E2E tests for Tint and

This CL splits the sem::Struct and sem::StructMember classes into having
a base class and a sem variant. The sem variant contains the
`ast::Declaration` for that sem node. This will allow the base classes
to move into the type hierarchy and keep the sem specific requirements
in the sem folder.

Nothing uses these, and the mutability of these breaks
const-correctness.
Switch functions that used to return `const utils::Vector<T, N>&`
to returning `utils::VectorRef<T>`. Removes the templated size from the
public interface.
Replace all `const utils::VectorRef<T>&` with `utils::Vector<T>`,
there's no point in using yet another level of pointer indirection.

This CL moves the ArrayCount from a variant to use inheritance. This
will allow the sem to have different array count classes from the IR.
The ArrayCounts, similar to types, are unique across the code base and
are provided by the TypeManager.

Overriding the alignment to 1 would cause nested structures to be
incorrectly laid out. The fix: Don't override the alignment.
All struct layout validation works on the sem offsets, so none of this
has to change.
