target/arm: Check NaN mode before silencing NaN
If the CPU is running in default NaN mode (FPCR.DN == 1) and we execute
FRSQRTE, FRECPE, or FRECPX with a signaling NaN, parts_silence_nan_frac() will
assert due to fpst->default_nan_mode being set.
To avoid this, we check to see what NaN mode we're running in before we call
floatxx_silence_nan().
