S/390: Remove unused expanders from vx-builtins.md

Browse Source 
These expanders are currently not used.  The vecintrin.h header file
expands e.g. vec_ceil directly to the vfidb low-level builtin.

gcc/ChangeLog:

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

	* config/s390/vx-builtins.md ("vec_ceil", "vec_floor")
	("vec_trunc", "vec_roundc", "vec_round"): Remove expanders.
