[RISCV] Precommit test for D130251

[RKSimon]

LGTM with one minor about test names (sorry I just find it difficult to keep test files 'tidy' with names like test1 ... test2 ... test_3 etc.).

llvm/test/CodeGen/RISCV/rotl-rotr.ll

325

for test names - its better to use real numbers based off the mask instead of just iterating the test#

so maybe rotl_32_mask_63_mask_31 ?

[• pcwang-thead]

Add tests which use or instruction but won't modify the masked bits.

[• pcwang-thead]

Rename functions.

@craig.topper @pcwang-thead You might want to review theses tests as the out of bounds shifts means they generate poison (which is exploited by rGae60706da07a128) - maybe use fshl/fshr intrinsics?
