dan sinclair f2b8b6e873 Emit validation errors after outputing result.
This Cl removes the SPIR-V validation errors to emit after the desired
output format. This means a SPVASM output will have the error at the
bottom making it more visible.

dan sinclair 435916e544 [spirv-writer] Fixes to constant constructor determination.
The change from `cast` to type constructor casts causes our current
determination if a constructor is constant to no longer be correct.

This Cl updates the determination to match the current spec and adds a
bunch of unit tests to verify the behaviour..

dan sinclair 4311dd05c8 [spirv-writer] Fix accessing array of non-scalars.
Currently, if we access an array of non-scalar items we'll incorrectly
emit an OpVectorExtractDynamic which will fail as the result is not
scalar.

This CL updates the array accessor code such that if the base array is
an array of non-scalars we'll do load of the array and then access chain
into the loaded variable.

dan sinclair 25f883520e [spirv-writer] Remove push_preamble
The push_preamble method was dealing with multiple sections of the
SPIR-V binary layout. As we changed the way things write (like
extensions getting written later) the preamble section was ending up in
incorrect order.

This CL replaces push_preamble with push methods for each of the
sections at the start of the SPIR-V module which should fixup the
ordering issue.

dan sinclair 5c948e4f8f [transform] Move the transform folder
This CL moves the transform folder from src/ast to src/. The transforms
operate on the AST, but they aren't part of the AST so I think the top
level folder makes more sense.

This will possibly cause issues when rolling if the transform is being
used.
