 I'm trying to write a unit test for the graph coloring register allocator
 and to start I'm trying to write a function (mostly modeled on
 hscCompileCmmFile and cmmNativeGen) that will compile a cmm file and
 return register allocation stats (that can then be asserted against).  It
 should be less cumbersome to use than cmmNativeGen.
