Issues, related to new feature DMD

Checklist

• DMD tests are missed CI
  CMakelists were not modified (fix some DMD issues #959).
• Sometimes test return info = -8 or info = - 10.
  Variable SSUM is not initialized before call of LASSQ, but it should be (fix some DMD issues #959).
• Tests for DMD are PASSED in any case
  Test always writes into stdout, return code is 0 even some checks are failed.
• stderr is not empty
  Message The following floating-point exceptions are signalling: IEEE_OVERFLOW_FLAG IEEE_UNDERFLOW_FLAG arises. Maybe it is not a big problem, but it is first not-empty stderr of LAPACK tests, as I see.

Ironically it appears to be the overflow protections that trigger the IEEE_OVERFLOW - code like IF ( SCALE .GE. (OFL / ROOTSC) ) where OFL is the overflow threshold returned by slamch/dlamch and ROOTSC (square root of SSUM) is smaller than one... (same problem also in ?GEJSV called by ?GEDMD )
