Squashed with commit f842bdd7a97e9fef7513a266d641cac72d5f97cc

gcc/ChangeLog:

	* config.in: Regenerate.
	* config/s390/s390.c (print_operand): Emit vector alignment hints
	for target z13, if AS accepts them.  For other targets the logic
	stays the same.
	* config/s390/s390.h (TARGET_VECTOR_LOADSTORE_ALIGNMENT_HINTS): Define
	macro.
	* configure: Regenerate.
	* configure.ac: Check HAVE_AS_VECTOR_LOADSTORE_ALIGNMENT_HINTS_ON_Z13.

gcc/testsuite/ChangeLog:

	* gcc.target/s390/vector/align-1.c: Change target architecture
	to z13.
	* gcc.target/s390/vector/align-2.c: Change target architecture
	to z13.
