  [InstSimplify] Refactor invariant.group load folding

Currently strip.invariant/launder.invariant are handled by
constructing constant expressions with the intrinsics skipped.
This takes an alternative approach of accumulating the offset
using stripAndAccumulateConstantOffsets(), with a flag to look
through invariant.group intrinsics.
