michaelselehov e2f92a324b [AA] Teach getModRefInfo(FenceInst) to consult the AA chain (#192043) ...

Extend the AA chain (Concept / Model / AAResultBase) with a
getModRefInfo(FenceInst) overload, mirroring the existing CallBase path.
Implement it in ScopedNoAliasAAResult so that !noalias metadata on
fences is respected. Previously, AAResults::getModRefInfo(FenceInst)
only checked getModRefInfoMask and ignored individual AA passes.
