calls. The pass visits all external functions in the module and determines
if such function calls can be optimized. The optimizations are specific to
the library calls involved. This initial version only optimizes calls to
exit(3) when they occur in main(): it changes them to ret instructions.

Completely rework the 'setcc (cast x to larger), y' code.  This code has
the advantage of implementing setcc.ll:test19 (being more general than
the previous code) and being correct in all cases.

This allows us to unxfail 2004-11-27-SetCCForCastLargerAndConstant.ll,
and close PR454.

USEDLIB as the variable to which "CBackend" is appended. The surrounding
if clause is safe because currently the configure script ensures that the
CBackend target is always added to TARGETS_TO_BUILD. By using a non-hard
coded construct in the makefile, we gain uniformity and the ability to
change the default set of targets by only changing the configure script.
