For all tests some extra code was optimized, GCC-C-execute has some more
inlining after

799033d8c5 Reland "[SLP] Consider alternatives for cost of select instructions." 
This reverts the revert commit a1b53db32418cb6ed6f5b2054d15a22b5aa3aeb9.

This patch includes a fix for a reported issue, caused by
matchSelectPattern returning UMIN for selects of pointers in
some cases by looking to some connected casts.

For now, ensure integer instrinsics are only returned for selects of
ints or int vectors.
