AA: Use generic intrinsics for tests instead of target specific ones Update a few tests to use llvm.masked.load/store instead of arm neon vector loads and stores, and move the tests that are actually specific to those arm intrinsics to their own files. This lets us mark the tests that use target specific intrinsics as requiring those targets. llvm-svn: 302972

[ModRefInfo] Add must alias info to ModRefInfo. Summary: Add an additional bit to ModRefInfo, ModRefInfo::Must, to be cleared for known must aliases. Shift existing Mod/Ref/ModRef values to include an additional most significant bit. Update wrappers that modify ModRefInfo values to reflect the change. Notes: * ModRefInfo::Must is almost entirely cleared in the AAResults methods, the remaining changes are trying to preserve it. * Only some small changes to make custom AA passes set ModRefInfo::Must (BasicAA). * GlobalsModRef already declares a bit, who's meaning overlaps with the most significant bit in ModRefInfo (MayReadAnyGlobal). No changes to shift the value of MayReadAnyGlobal (see AlignedMap). FunctionInfo.getModRef() ajusts most significant bit so correctness is preserved, but the Must info is lost. * There are cases where the ModRefInfo::Must is not set, e.g. 2 calls that only read will return ModRefInfo::NoModRef, though they may read from exactly the same location.
