  [AArch64] Mark aarch64_set_fpmr as IntrWriteMem (#146353)

llvm.aarch64.set.fpmr only writes to inaccessible memory. Tag it with
the IntrWriteMem and IntrInaccessibleMemOnly properties so the optimiser
can treat it as a pure write.

The original patch did not add this property, causing the intrinsic to
be conservatively treated as readwrite. This commit fixes that.
