	* rtems/src/regioncreate.c, rtems/src/regiondelete.c,
	rtems/src/regionextend.c, rtems/src/regiongetfreeinfo.c,
	rtems/src/regiongetinfo.c, rtems/src/regiongetsegment.c,
	rtems/src/regiongetsegmentsize.c, rtems/src/regionresizesegment.c,
	rtems/src/regionreturnsegment.c: Restructed to move the OBJECTS_LOCAL
	case to the top of the switch statement, have a single exit with one
	call to _RTEMS_Unlock_allocator and eliminate the fall-through return
	of RTEMS_INTERNAL_ERROR.  These changes produced simplier assembly
	code and allowed for complete test coverage.
