Actually, that may have been a fault in my test. When I started, I
didn't have 32 in the constant, but something else. When I tried to
reproduce the problem with 32 it always seems to generate the shift.

Compiling with no -O option or with -O0 causes the helper function to
be called. Compiling with -O1, 2, 3 or s causes a divide by 32 to be
replaced with a shift.

I was using -Os when I hit it.
