This switches to the workaround that HSA defaults to
for the mesa path.
This should be applied to the 4.0 branch.

Canonicalize a select with a constant to the false side. This
enables more instruction shrinking opportunities since an
inline immediate can be used for the false side of v_cndmask_b32_e32.
This seems to usually be better but causes some code size regressions
in some tests.
