[Bug tree-optimization/96930] Failure to optimize out arithmetic with bigger size when it can't matter with division transformed into right shift

--- Comment #5 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
I can't reproduce that.
I get:
        movl    %edi, %eax
        movl    %esi, %ecx
        shrl    %cl, %eax
        ret
for that function, and LLVM emits the same code with the first two insns
swapped.
Only in baz above I get:
        movl    %edi, %eax
        movl    %esi, %ecx
        shrq    %cl, %rax
        ret
which is the 64-bit shift instead (but I doubt on x86_64 there is any
difference except the 1 byte in code size).
