Use ResetDef to prevent from removing necessary stores for x86 long-to-fp.

X86 long-to-fp needs the source operand in the memory.
Later on, NullifyRange may remove the stores and then lead to incorrect
long-to-fp conversions.
To fix this bug, ResetDef is called after flushing source to the memory
for x86 long-to-fp.
