#5233: Support specifying the assembly that should be generated

---------------------------------+------------------------------------------
We want to make sure that native code generator optimizations, like primop
unrolling, always fire. We can do this by allowing the programmer to
specify what assembly should be generated for a particular snippet of Cmm.
The programmer gives a snippet 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 the expected assembly output:
{{{
callMemcpy:
movq ; Move arguments into place
movq
movl
movl
call memcpy
}}}
The expected output shouldn't mention specific register names as these are
likely to change.
