BUG: linalg: fix corner-case behavior of cond() + use SVD if possible
Make np.linalg.cond(A, p) always use SVD for p=+-2 and not only p=None.
Ensure inf is returned instead of nan when the condition number diverges
for +/-2 norm.
Ignore errors when inverting matrices for p = +-1, 'fro', +-inf, so that
spurious LinAlgErrors are not raised. In those cases, report
non-invertible matrices as having cond=inf.
Add additional tests for cond().
