  -----------
  Fix warnings with cmake's MINSIZEREL build type

- 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 assert can return then many warnings are
  produced due to this unexpect path.
- Remove defining NDEBUG for REL build types if using the MSC compiler
