Thanks for committing the patches and for the regression tests.

As explained in
http://lists.ximian.com/pipermail/mono-devel-list/2009-January/030603.html I've
changed OP_LCONV_TO_R_UN because I believe it does several unecessary
operations.

Doing some performance tests may be worth it but I don't really see any reason
to round-trip 80-bit FP values from the FP stack to the normal stack that
causes nothing to change other than lost CPU cycles.
