s390: Fix dealing with HF vector modes in s390_secondary_reload

Initial HF mode support was added in commit r16-6682-g5d6d56d837c which
is missing HF vector mode support when dealing with secondary reloads
for instructions which do not accept relative operands.

gcc/ChangeLog:

	* config/s390/s390.cc (s390_secondary_reload): Add cases for HF
	vector modes.
	* config/s390/s390.md: Add modes V{1,2,4,8}HF to mode iterator
	ALL.
