[RISC-V] Fix more fallout from combine.c changes
Trivial fallout from the recent combine work. We end up with a srai rather
than an xor in some of the saturation sequences. Both variants look equally
performant, so I'm just adjusting the expected test output.
gcc/testsuite
* gcc.target/riscv/sat/sat_s_sub-1-i64.c: Update expected output.
* gcc.target/riscv/sat/sat_s_sub-2-i64.c: Likewise.
* gcc.target/riscv/sat/sat_s_sub-3-i64.c: Likewise.
* gcc.target/riscv/sat/sat_s_sub-4-i64.c: Likewise.
