math: improve sqrt for ppc64le,ppc64
The existing implementation uses code written in Go to
implement Sqrt; this adds the assembler to use the sqrt
instruction for Power and makes the necessary changes to
allow it to be inlined.
The following tests showed this relative improvement:
benchmark delta
BenchmarkSqrt -97.91%
BenchmarkSqrtIndirect -96.65%
BenchmarkSqrtGo -35.93%
BenchmarkSqrtPrime -96.94%
Fixes #14349
