[Bug fortran/26025] New: Optionally use BLAS for matmul

[tkoenig at gcc dot gnu dot org]

There should be a flag for replacing our home-grown
matmul and dot_product with calls to BLAS.  If the user has
installed an optimized BLAS version, this could be a huge win.

There was some discussion of this on the mailing list, but no PR
that I could find.

Something like -fblas-intrinsics (and -fblas-f2c, for complex)
would be good.
