3f13486e08 Usability improvements for mmqa: 
* -i option (MPS_INCLUDE_DIR) now defaults to the code directory relative to the test harness location.
* -p option (PLATFORM) is now a six-character platform code for consistency with the rest of the MPS.
* New -v option (VARIETY) for specifying cool/hot/rash.
* -l option (MPS_LINK_OBJ) now defaults to the appropriate object file for the platform and variety.
* The object file is built automatically.
* If $Id$ of a test file is longer than 70 characters, cut characters out of the middle rather than off the end.
* Eliminate obsolete option -prod (MPS_PRODUCT).
* Support for FreeBSD.

419ba15d42 Change 192148 (the fix for job004017) caused the hot variety to compile out assertions on the critical path in manual-allocation-bound programs, which caused various mmqa test cases to fail in the hot variety. move these failing tests to the coolonly testset.
