Comment (by simonpj):

 ALl constraint solving is done on the original source programming.  No
 inlining, nothing.  When simplification/inlining starts, constraint
 solving is over.  Nothign more than that.

 The flag controls only what happens at constraint-solving time.  Maybe it
 should be better documented
