 Thanks.  By the way, does the JIT optimizer translate IL to IL first
 or are all optimizations architecture-specific?
 If it's to IL, would it be possible to add a -O flag to monodis so we
 can see the optimized output?

+This specific optimization is done in arch-independent code when the
+IL code is translated to the jit internal representation. As this is
+internal to the jit there is no way to make such a monodis option (and
+it wouldn't make sense, since monodis is supposed to disassemble the
+code as it is).
+There are vague plans to use the Cecil library to implement IL->IL
+transformations and optimizations. So you may want to wait for that or
+help its implementation. The plans are vague because Cecil is very
+incomplete and the possible optimizations are very limited so it's not
+clear if someone will spend the time on it.
