I ran on PA-RISC (HP-UX 11.00) and it looked OK. I got three failures
but they fail with and without my change.
The change does not appear to have affected the code generated on HPPA,
an integer division with loop invariant arguments never gets hoisted out
of the loop on PA and a constant function with loop invariant arguments
always gets hoisted out of the loop on PA, with our without my change
and with or without generating PIC code.
