Quick Compiler function renaming

Move the Quick compiler's function naming to Art coding conventions. Will
be done is pieces: names first, then arguments and locals.  Also removed
some dead code and marked statics for the top level source files

No logic changes aside from eliminating a few useless exported "oat"
routines.
