  [PowerPC] Add builtins for xvtdiv(dp|sp) and xvtsqrt(dp|sp).

Summary: This patch implements the builtins for xvtdivdp, xvtdivsp, xvtsqrtdp, xvtsqrtsp.
The instructions correspond to the following builtins:
int vec_test_swdiv(vector double v1, vector double v2);
int vec_test_swdivs(vector float v1, vector float v2);
int vec_test_swsqrt(vector double v1);
int vec_test_swsqrts(vector float v1);
This patch depends on D88274, which fixes the bug in copying from CRRC to GPRC/G8RC.
