* tc-i386.c (cpu_arch): Add .8087, .287, .387, .no87, .nommx,
.nosse, and .noavx.
(cpu_flags_and_not): New.
(set_cpu_arch): Check whether sub-architecture specified is a
feature disable.
(md_parse_option): Likewise.
(parse_real_register): Don't return floating point register
when x87 functionality is disabled.
(md_show_usage): Add new sub-options.
* doc/c-i386.texi: Update with new command line sub-options.

* i386-dis.c (fgrps): Correct annotation for feni/fdisi. Add
frstpm.
* i386-gen.c (cpu_flag_init): Add FP enabling flags where needed.
(cpu_flags): Add Cpu8087, Cpu287, Cpu387, Cpu687, and CpuFISTTP.
(set_bitfield): Expand CpuFP to Cpu8087|Cpu287|Cpu387.
* i386-opc.h (Cpu8087, Cpu287, Cpu387, Cpu687, CpuFISTTP):
Define.
(union i386_cpu_flags): Add cpu8087, cpu287, cpu387, cpu687,
and cpufisttp.
* i386-opc.tbl: Qualify floating point instructions by their
respective CpuXXX flag. Fix fucom{,p,pp}, fprem1, fsin, fcos,
and fsincos to be avilable only on 387. Fix fstsw ax to be
available only on 287+. Add f{,n}eni, f{,n}disi, f{,n}setpm,
and frstpm.
* i386-init.h, i386-tbl.h: Regenerate.
