FloatBug2.il

Actual results:
0xffffffffffffff
0xffffffffffffff
0xffffffffffffff

Expected results:
0xffffffffffffff
0x100000000000000
0x100000000000000

Maybe conv.r8 on a float64 should also be implemented for x86 if it's after a
function call or after argument load (if these latter are stored on FP stack)
because external (native) code can put 80-bit values on the FP stack. I'll
check this with MS.NET and if it does implement this conversion I'll open a new
bug.
