Interpreter_FloatingPoint: Clear FPSCR.FI and FPSCR.FR if an SNaN is an input to fres
In the PEM manual, within Table 3-12, which lists what should occur for
invalid operation exceptions, the FPSCR.FI and FPSCR.FR bits are listed
as "Cleared" for when FPSCR.VE is unset and set. So we clear these bits
as well to match hardware behavior.
