[RISC-V] Fix scan test output after recent path-splitting changes

The recent path splitting changes from Andrew result in identifying more
saturation idioms instead of just identifying an overflow check.  As a result
many of the tests in the RISC-V port started failing a scan check on the
.expand output.

As expected, identifying a saturation idiom is more helpful than identifying an
overflow check and the resultant code is better based on my spot checks.

So the right thing to do is to expect more saturation intrinsics in the .expand
output.

I've verified this fixes the regressions for riscv32-elf and riscv64-elf.
Pushing to the trunk.
