Relax check against commuting XOR and ASHIFTRT in combine.c
gcc/:
* combine.c (simplify_shift_const_1): Allow commuting (ashiftrt (xor))
when result_mode == shift_mode.
gcc/testsuite/:
* gcc.dg/combine_ashiftrt_1.c: New test.
* gcc.dg/combine_ashiftrt_2.c: Likewise.
* gcc.target/aarch64/singleton_intrinsics_1.c: Remove scan-assembler
workarounds for cmge.
* gcc.target/aarch64/simd/int_comparisons_1.c: Likewise; also check for
absence of mvn.
