     Make it possible to test the generated assembly

     This test framework feature is inspired by a similar feature in LLVM.
     The programmer writes a bit of Cmm

         #include "Cmm.h"

         // Large memcpy's should lower to calls.
         callMemcpy
         {
           W_ dst, src;
           prim %memcpy(dst "ptr", src "ptr", 1024, 4) [];
         }

     and asserts what the generated assembly should look like, modulo
     register naming.

         callMemcpy:
         movq  ; Move arguments into place
         movq
         movl
         movl
         call memcpy

     Patch edited and updated by Simon Marlow, and I also added a test for
     unrolling memcpy and a simple constant-propagation test.
