[PATCH, committed] PR 42694: Optimize pow (x, 0.25), pow (x, 0.75), and pow (1./6.)


I committed the following patch for 42694 that adds some optimizations for pow,
particularly pow (x, 0.75) that shows up in some Fortran code (bwaves).

The patch was discussed and approved in January when stage1 opened up:
