[InstCombine] Fold bitwise logic with intrinsics (#77460)

This patch does the following folds:
```
bitwise(fshl (A, B, ShAmt), fshl(C, D, ShAmt)) -> fshl(bitwise(A, C), bitwise(B, D), ShAmt)
bitwise(fshr (A, B, ShAmt), fshr(C, D, ShAmt)) -> fshr(bitwise(A, C), bitwise(B, D), ShAmt)
bitwise(bswap(A), bswap(B)) -> bswap(bitwise(A, B))
bitwise(bswap(A), C) -> bswap(bitwise(A, bswap(C)))
bitwise(bitreverse(A), bitreverse(B)) -> bitreverse(bitwise(A, B))
bitwise(bitreverse(A), C) -> bitreverse(bitwise(A, bitreverse(C)))
