Post-Review Cleanup:
...
* Fix comments at top of file
* Change algorithm for running the call optimizations from n*n to something
closer to n.
* Use a hash_map to store and lookup the optimizations since there will
eventually (or potentially) be a large number of them. This gets lookup
based on the name of the function to O(1). Each CallOptimizer now has a
std::string member named func_name that tracks the name of the function
that it applies to. It is this string that is entered into the hash_map
for fast comparison against the function names encountered in the module.
* Cleanup some style issues pertaining to iterator invalidation
* Don't pass the Function pointer to the OptimizeCall function because if
the optimization needs it, it can get it from the CallInst passed in.
* Add the skeleton for a new CallOptimizer, StrCatOptimizer which will
eventually replace strcat's of constant strings with direct copies.

A new pass to provide specific optimizations for certain well-known library
...
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.

Make the CBackend actually get included in llc by using USEDLIBS instead of
...
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.
