Fix typo in <code>v1ti3.

For evex encoding vp{xor,or,and}, suffix is needed.

Or there would be an error for
vpxor %xmm0, %xmm31, %xmm1

Error: unsupported instruction `vpxor'

gcc/ChangeLog:

	* config/i386/sse.md (<code>v1ti3): Add suffix and replace
	isa attr of alternative 2 from avx to avx512vl.

gcc/testsuite/ChangeLog:
