Quick compiler source reorganizatio - part 1
A step towards cleanup of the quick compiler source. In this
CL we rename all files to Art standards, combine some of the
old target-specific files that may have made sense in the
JIT, but no longer do. Also removed some codegen/<target>/
subdirectories, combined and deleted some existing files.
Still quite a bit of work to do in cleaning up header files,
getting some better consistency in what codegen functions
go where. That will happen in later CLs.
No logic changes in this CL - just renaming and moving stuff around
