This patch adds the Clang builtins and LLVM intrinsics to load and store vector pairs.
Depends on D90616
Add builtin tests
Add support for the paired load/store intrinsics in PPCLoopInstrFormPrep
Rebase patch and add Sema check test case for the builtins
Fix unaligned load/store select
There's alot of nested ifs, would it be possible to refactor to have some early exits instead?
Can we add -ppc-asm-full-reg-names and update the checks to also ensure the reg info is accurate?
is this needed since we have the triple on the run line?
Simplify control flow and improve test cases
Thanks for fixing for tests and formatting. LGTM if there are no other concerns.
