x86: disambiguate disassembly of certain AVX512 insns

x86: disambiguate disassembly of certain AVX512 insns

Certain conversion operations as well as vfpclassp{d,s} are ambiguous
when the input operand is in memory and no broadcast is being used.
While in Intel mode this gets resolved by printing suitable operand
size modifiers, AT&T mode need mnemonic suffixes to be added.

	* gas/i386/avx512dq.d: Add 'z' suffix to vfpclassp{d,s} non-
	register, non-broadcast cases.
	* gas/i386/x86-64-avx512dq.d: Likewise.
	* gas/i386/avx512dq_vl.d: Add 'x' and 'y' suffixes to
	vcvt{,u}qq2ps and vfpclassp{d,s} non-register, non-broadcast
	cases.
	* gas/i386/x86-64-avx512dq_vl.d: Likewise.
	* gas/i386/avx512f_vl.d: Add 'x' and 'y' suffixes to
	vcvt{,t}pd2{,u}dq and vcvtpd2ps non-register, non-broadcast
