Support APX NF
For the case when NDD and NF are both 0 in evex-promoted format,
we will fully support and test it in another patch.
gas/ChangeLog:
* NEWS: Support Intel APX NF.
* config/tc-i386.c (enum i386_error): Add unsupported_nf.
(struct _i386_insn): Add has_nf.
(is_apx_evex_encoding): Ditto.
(build_apx_evex_prefix): Encode the NF bit.
(md_assemble): Handle unsupported_nf.
(parse_insn): Handle Prefix_NF and report bad for illegal combination.
(can_convert_NDD_to_legacy): Replace i.tm.opcode_modifier.nf with i.has_nf.
(match_template): Support D for APX_F insns and check NF support.
* testsuite/gas/i386/x86-64-apx-evex-promoted-bad.d: Add bad test for NF bit.
* testsuite/gas/i386/x86-64-apx-evex-promoted-bad.s: Ditto.
* testsuite/gas/i386/x86-64-apx-inval.l: Ditto.

add new instruction imul, popcnt, tzcnt and lzcnt to EVEX table.
* i386-dis-evex-reg.h: Ditto.
* i386-dis.c (struct instr_info): Add nf.
(struct dis386): Add "NF" for EVEX.NF.
(get_valid_dis386): Set ins->vex.nf and report bad-nf for illegal case.
