 I am not sure what do you mean. Do you want ngen-ed output or normal
 MSIL assembly ?

+The IL code to see why we generate worse JIT code from their IL code,
+we don't care about their jit-generated code.
+Anyway, I added the support in the jit to use SSE2 instructions to
+convert to int and this makes the test go from 1850 to 800 on my
+system: this should cover pretty much all the difference with the
+mcs-compiled IL code.
