S/390: arch13: Support 32 bit fp-int vector converts

gcc/ChangeLog:

2019-04-02  Andreas Krebbel  <krebbel@linux.ibm.com>

	* config/s390/s390.md ("xde"): Extend mode attribute to vector
	types.
	* config/s390/vector.md (VX_VEC_CONV_BFP, VX_VEC_CONV_INT): New
	mode iterators.
	("floatv2div2df2", "floatunsv2div2df2", "fix_truncv2dfv2di2")
	("fixuns_truncv2dfv2di2"): Enhance with mode iterator to also
	support 32 bit fp-int conversions. Rename to ...
	("float<VX_VEC_CONV_INT:mode><VX_VEC_CONV_BFP:mode>2")
	("floatuns<VX_VEC_CONV_INT:mode><VX_VEC_CONV_BFP:mode>2")
	("fix_trunc<VX_VEC_CONV_BFP:mode><VX_VEC_CONV_INT:mode>2")
	("fixuns_trunc<VX_VEC_CONV_BFP:mode><VX_VEC_CONV_INT:mode>2"):
	... to these.
