[InstCombine] try to narrow shifted bswap-of-zext (2nd try)
The first attempt at this missed a validity check.
This version includes a test of the narrow source
type for modulo-16-bits.
Original commit message:
This is the IR counterpart to 370ebc9d9a573d6
which provided a bswap narrowing fix for issue #53867.
Here we can be more general (although I'm not sure yet
what would happen for illegal types in codegen - too
rare to worry about?):
https://alive2.llvm.org/ce/z/3-CPfo
This will be more effective if we have moved the shift
after the bswap as proposed in D122010, but it is
independent of that patch.
