Matthias Braun 004fe6bf83 DAGCombiner: StoreMerging: Fix bad index calculating when adjusting mismatching vector types
This fixes a case of bad index calculation when merging mismatching
vector types. This changes the existing code to just use the existing
extract_{subvector|element} and a bitcast (instead of bitcast first and
then newly created extract_xxx) so we don't need to adjust any indices
in the first place.
