mips-msa.md (msa_fmax_a_<msafmt>, [...]): Introduce mode interator for if_then_else. 

gcc/
	* config/mips/mips-msa.md (msa_fmax_a_<msafmt>, msa_fmin_a_<msafmt>,
	msa_max_a_<msafmt>, msa_min_a_<msafmt>): Introduce mode interator for
	if_then_else.
	(smin<mode>3, smax<mode>3): Change operand print code from 'B' to 'E'.
