Compiler: LIR restructuring

Continuing restructuring of the compiler.  In this installment,
all LIR reverences are moved from compiler_ir down to quick.  Further,
all Portable data is moved to from compiler_ir down to portable.

In short, the great dumping ground of CompilationUnit has been
split into three smaller dumping grounds of MIRGraph, Codegen
and MIRConverter.  From here, subsequent CLs will repartition
those smaller dumping grounds into (hopefully) more coherent classes.
As a result, most function signatures have been altered to remove
the passing around of a CompilationUnit* pointer.
