  Log Message:
  -----------
  fix warnings in MINSIZEREL build types

- explicitly define optimization flags for cmake's MINSIZEREL build
  type.  Cmake by default includes -DNDEBUG.  This results in assert
  being defined to do nothing.  Dyninst use asserts as a fatal error
  reporting mechanism and expects assert to not return if the condition
  is always false.  If it can return then many warnings are produced
  due to this unexpect path.
- remove defining NDEBUG for REL build types if using the MSC compiler
