Sam Elliott b342539dcd [RISCV] Fix ICE in isDesirableToCommuteWithShift ...

Summary:
Ana Pazos reported a bug where we were not checking that an APInt would
fit into 64-bits before calling `getSExtValue()`. This caused asserts when
compiling large constants, such as i128s, as happens when compiling compiler-rt.

This patch adds a testcase and makes the callback less error-prone.
