[GVN] Fix metadata combining for non-local loads

Make MaterializeAdjustedValue() responsible for adjusting load
metadata in all cases, so it also covers the non-local case.

In conjunction with that, we no longer need to call
patchReplacementInstruction() for the local case, which would
unnecessarily drop metadata if the replacement value just happened
to be a load (without actual load CSE).
