In any case, this looks like a clear backend bug, as it allows const_int 32 in
the operand (through the use of M constraint), but then doesn't handle it at
all in arm_output_shift (it forces use of %S3 on it and that requires 0 .. 31
constant, not 0 .. 32). And while the code has undefined behavior, if you
never invoke it, you should still be able to have it in a valid program.
