  -----------
  [EarlyCSE] Handle masked loads and stores

Extend the handling of memory intrinsics to also include non-
target-specific intrinsics, in particular masked loads and stores.

Invent "isHandledNonTargetIntrinsic" to distinguish between intrin-
sics that should be handled natively from intrinsics that can be
passed to TTI.

Add code that handles masked loads and stores and update the
testcase to reflect the results.
