Hi:
The vect-strided-shift-1.c test fails on MIPS target.
FAIL: gcc.dg/vect/vect-strided-shift-1.c -mpaired-single
scan-tree-dump-times vect "vectorized 1 loops in function" 1 (found 0
times)
FAIL: gcc.dg/vect/vect-strided-shift-1.c -flto -ffat-lto-objects
-mpaired-single scan-tree-dump-times vect "vectorized 1 loops in
function" 1 (found 0 times)
Because the MIPS paired single insns only support for float
operations, not suite for this test.
added dg-skip-if directives on it for skip -mpaired-single option.
Ok for commit ?

OK. Though this may point to a need to have a new target-supports routine.
