  Log Message:
  -----------
  [LLVMABI] Add support for SVE types in the LLVM ABI library (#221375)

This change extends the LLVM ABI library's VectorType to be able to
describe SVE types and updates Clang's QualTypeMapper to map them.

The AArch64 target info class in the ABI library is still a work in
progress. It will continue to report "not yet implemented" for function
signatures involving SVE types. This change is a neceasary prerequisite
for correctly handling them or correctly deferring handling of these
specific types.
