[DAGCombiner] add early exit for store merging of truncs

This should be NFC in terms of output because the endian
check further down would bail out too, but we are wasting
time by waiting to that point to give up. If we generalize
that function to deal with more than i8 types, we should
not have to deal with the degenerate case.
