[luau] Useful Tool: Compiler Cache

Anyone tried this before?  This program is a wrapper for your compiler that
caches .o files for later re-use.  He claims it is stable and safe.  If this
is so, then I can see this to be a very useful tool.

It parses all pre-processor stuff to be sure all code, even header .h files
are unchanged before using the cached output.  It claims to be smart enough
to avoid recompiling in the event of changes to comments.
