David Wood a2f7f3c1eb ty_utils: lower tuples to ScalableVector repr ...

Instead of just using regular struct lowering for these types, which
results in an incorrect ABI (e.g. returning indirectly), use
`BackendRepr::ScalableVector` which will lower to the correct type and
be passed in registers.

This also enables some simplifications for generating alloca of scalable
vectors and greater re-use of `scalable_vector_parts`.

A LLVM codegen test demonstrating the changed IR this generates is
included in the next commit alongside some intrinsics that make these
tuples usable.
