At least if the compiler also recognizes that oy and oz are constant...
If the typed constants are declared as read only, we could treat them as real
constants. Maybe at
least in -O4 mode?
They're plain local variables that are assigned once and never changed.
That said, simply treating them (and floor(oy)/floor(oz)) as constants
does not improve the generated code very much. There's probably another
similar thing that causes a large part to be simplified/evaluated away
in the C version.
