x86: don't require operand size specification for AVX512 broadcasts
Certain conversion operations as well as vfpclassp{d,s} are ambiguous
when the input operand is in memory. That ambiguity, however, doesn't
apply when using broadcasts (the destination operand size can be
induced from the broadcast specifier).

* config/tc-i386.c (match_mem_size): Also allow no size
specification when broadcasting.

* gas/i386/avx512dq.s: Drop 'z' suffix from vfpclassp{d,s} in
some AT&T and all Intel cases.
* gas/i386/x86-64-avx512dq.s: Likewise.
* gas/i386/avx512dq_vl.s: Drop 'x' and 'y' suffixes from
vcvt{,u}qq2ps and vfpclassp{d,s} in some AT&T and all Intel
cases.
* gas/i386/x86-64-avx512dq_vl.s: Likewise.
* gas/i386/avx512f_vl.s: Drop 'x' and 'y' suffixes from
vcvt{,t}pd2{,u}dq and vcvtpd2ps in some AT&T and all Intel
cases.
* gas/i386/x86-64-avx512f_vl.s: Likewise.
