[InstCombine] Add constant combines for `(urem/srem (shl X, Y), (shl X, Z))`
Forked from D142901 to deduce more `nsw`/`nuw` flag for the output
`shl`.
We can handle the following cases + some `nsw`/`nuw` flags:
The rationale for doing this all in `InstCombine` rather than handling
the constant `shl` cases in `InstSimplify` is we often create a new
instruction because we are able to deduce more `nsw`/`nuw` flags than
the original instruction had.
