Try to use the underlying source registers. This enables legalization in more cases where some irregular operations are widened and others narrowed. This seems to make the test_combines_2 AArch64 test worse, since the MERGE_VALUES has multiple uses. Since this should be required for legalization, a hasOneUse check is probably inappropriate (or maybe should only be used if the merge is legal?). llvm-svn: 353121
