S/390: Support vector alignment hints
    
    This patch adds the vector alignment hints to the vector load and
    store instructions as documented in the IBM z14 Principles of
    Operations manual:

    2018-10-23  Andreas Krebbel  <krebbel@linux.ibm.com>
    
    	* config/tc-s390.c (md_gather_operands): Fix for optional operands
    	following memory addresses.
    	* testsuite/gas/s390/zarch-arch12.d: Add regexp checks for new
    	instruction variants.
