[PATCH] IBM Z: ldist-{rawmemchr, strlen} tests require vector extensions

[Stefan Schulze Frielinghaus]

The tests require vector extensions which are only available for z13 and
later while using the z/Architecture.

Bootstrapped and regtested on IBM Z.  Ok for mainline?

gcc/testsuite/ChangeLog:

	* gcc.dg/tree-ssa/ldist-rawmemchr-1.c: For IBM Z set arch to z13
	and use z/Architecture since the tests require vector extensions.
	* gcc.dg/tree-ssa/ldist-rawmemchr-2.c: Likewise.
	* gcc.dg/tree-ssa/ldist-strlen-1.c: Likewise.
	* gcc.dg/tree-ssa/ldist-strlen-3.c: Likewise.
