S/390: Add missing comments listing mnemonics. 

These were useful in the past but are currently lacking on a couple of
patterns.  Fixed with this patch.

gcc/ChangeLog:

2017-02-02  Andreas Krebbel  <krebbel@linux.vnet.ibm.com>

	* config/s390/s390.md: Add missing comments with the expanded
	mnemonics.
	* config/s390/vector.md: Likewise.
	* config/s390/vx-builtins.md: Likewise.
