Normalize all internal workaround methods to use spv prefix.
...
We have been interchanging spv and SPIRV_Cross_ for a while, which
causes weirdness since we don't explicitly ban SPIRV_Cross identifiers,
as these identifiers are generally used for interface variable
workarounds.

MSL: Don't use a bitcast for tessellation levels in tesc shaders.
...
`half` cannot be bitcasted to `float`, because the two types are not the
same size. Use an expanding cast instead.
We were already doing this for stores to the tessellation levels; why I
didn't also do this for loads is beyond me.

Mostly relevant when emitting buffers, so implement a 32-bit integer
scalar subset of the evaluator. Can be extended as needed to support
evaluating any specialization constant operation.

Overhaul how we deal with reserved identifiers.
...
- Do not silently drop reserved identifiers in the parser. This makes it
possible to reflect identifiers which are reserved by the
cross-compiler module.
- Instead of dropping the name, emit _RESERVED_IDENTIFIER_FIXUP in the
source to make it clear that a name has been rewritten.
- Document what is reserved and not.

MSL: Workaround broken vector -> scalar access chain in MSL.
...
On MSL, the compiler refuses to allow access chains into a normal vector type.
What happens in practice instead is a read-modify-write where a vector type is
loaded, modified and written back.
The workaround is to convert a vector into a pointer-to-scalar before
the access chain continues to add the scalar index.
