I've noticed a typo on the flag name, fixed thusly.

* config/i386/i386.md (truncsfbf2): Fix comment typo,
unsafte -> unsafe.
/* vcvtneps2bf16 doesn't honor SNAN, and turn sNAN into qNAN quietly,
and it always round to even.
- flag_unsafte_math_optimization is needed for psrld.
+ flag_unsafe_math_optimization is needed for psrld.
If we don't expect qNaNs nor sNaNs and can assume rounding
to nearest, we can expand the conversion inline as
(fromi + 0x7fff + ((fromi >> 16) & 1)) >> 16. */
