[X86] Add tests showing inability of vector non-temporal load/store intrinsic to force pointer alignment (PR33830) Clang specifies a max type alignment of 16 bytes on darwin targets, meaning that the builtin nontemporal stores don't correctly align the loads/stores to 32 or 64 bytes when required, resulting in lowering to temporal unaligned loads/stores. llvm-svn: 309382

[X86][AVX] Ensure vector non-temporal load/store intrinsics force pointer alignment (PR33830) Clang specifies a max type alignment of 16 bytes on darwin targets (annoyingly in the driver not via cc1), meaning that the builtin nontemporal stores don't correctly align the loads/stores to 32 or 64 bytes when required, resulting in lowering to temporal unaligned loads/stores. This patch casts the vectors to explicitly aligned types prior to the load/store to ensure that the require alignment is respected.
