Sam Tebbs e7f9d8e5c3 [AArch64] Lower alias mask to a whilewr (#100769) 
https://github.com/llvm/llvm-project/pull/100579 emits IR that creates a
mask disabling lanes that could alias within a loop iteration, based on
a pair of pointers. This PR lowers that IR to the WHILEWR instruction
for AArch64.
