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.
