Previous logic did not handle the case where the result bit size was between 32 and 64 bits inclusive. I updated the if-statements for more precise handling. An alternative solution would have been to abort FastISel in case the result type is not legal for FastISel. Resolves: #64222. This PR began as an investigation into the root cause of https://github.com/ziglang/zig/issues/20966. Godbolt link showing incorrect codegen on 20.1.0: https://godbolt.org/z/cEr4vY7d4.
