This patch fixes the test cases in
I've found the following bugs:
1. Return value of functions don't has to be rounded and is not rounded
by MS.NET either.
2. conv.r4 has to change precision (required by ECMA specs)
3. conv.r8 also has to change precision
I also reordered code in OP_LCONV_TO_R_UN_2 because there is no need to
allocate extra stack space and store and reload a 80-bit floating point
value. I just removed unnecessary code but please have a look at the
changes because I have little experience with the FPU.
Also note that the test in the bug report should be modified to be
platform independent and the above three bugs should be fixed on all
other platforms that has them.
