  Log Message:
  -----------
  [DebugInfo] Fixing CodeView assert related to lowerBound field of DISubrange.

    This is to fix CodeView build failure https://bugs.llvm.org/show_bug.cgi?id=47287
    after DIsSubrange upgrade D80197

    Assert condition is now removed and Count is calculated in case LowerBound
    is absent or zero and Count or UpperBound is constant. If Count is unknown
    it is later handled as VLA (currently Count is set to zero).
