dca16df666 lapack/gonum: fix bugs in Dgesvd and rewrite DgesvdTest 
- if condition for one the paths in workspace size calculation was
  misspelled
- return value from Dbdsqr was ignored in some paths, leaving it at
  false (failed) value
- if the input matrix A was rescaled, the output singular values have
  to be unscaled back. The code uses Dlascl which treats the s slice as
  a matrix. The column major reference treats it as minmn-by-1 matrix
  with the stride minmn, and this was not correctly translated in our
  row major implementation.

Also clean up the initial parameter checks.
