MIPS: math-emu: Don't pass qNaNs through quieting handlers
Don't call the `ieee754sp_nanxcpt' and `ieee754dp_nanxcpt' sNaN quieting
handlers for a qNaN supplied to floating-point format conversions or
SQRT.S/SQRT.D instructions, or for a qNaN produced out of a negative
operand supplied to SQRT.S/SQRT.D instructions. Return the qNaN right
away in these cases.
