79e06bf1 - [AMDGPU] Extended vector promotion to aggregate types. (#143784)

[AMDGPU] Extended vector promotion to aggregate types. (#143784) Extends the `amdgpu-promote-alloca-to-vector` pass to also promote aggregate types whose elements are all the same type to vector registers. The motivation for this extension was to account for IR generated by the frontend containing several singleton struct types containing vectors or vector-like elements, though the implementation is strictly more general.
