mat: use lapack64.Potri in Cholesky.InverseTo
...
Also,
- make tricky shadowing conversion from a SymDense to a TriDense more
explicit in Cholesky.ToSym,
- add a benchmark for InverseTo:
name old time/op new time/op delta
CholeskyInverseTo/n=10-4 10.8µs ± 2% 3.2µs ± 1% -70.16% (p=0.008 n=5+5)
CholeskyInverseTo/n=100-4 1.07ms ± 2% 0.51ms ± 2% -52.06% (p=0.008 n=5+5)
CholeskyInverseTo/n=1000-4 713ms ± 1% 315ms ± 1% -55.83% (p=0.008 n=5+5)
