The fix for BR 3392278:
aa29b1d93f5a assemble.c: Don't drop rex prefix from instruction itself
... would cause multiple REX prefixes to be emitted for some
instructions. Create a new flag to indicate that REX has already been
emitted, which can be cleared for each instance of an instruction.

It's been requested a long ago to handle '--v' option same was as
a regualar '-v'. From initial report
| NASM and yasm are in many respects compatible but yasm uses --v
| instead of -v for version. As often --v is used for version I
| end up using --v initially in NASM. This patch allows me to compile
| Mozilla apps which use yasm with NASM by merely renaming NASM to yasm
| so that the build environment does not have to be updated (Mozilla
| would not accept changes to allow use of NASM).

With broadcasting, EVEX.L'L should be matched even when EVEX.b is set.
Only in a case of embedded rounding, EVEX.L'L is ignored in matching
function since it becomes EVEX.RC.

emit_rex is supposed to write REX prefix into output stream
if needed, but we happen to drop it off on a first write
which breaks REX required instructions if TIMES directive
is used.
For example the code like
| times 4 movq xmm11, xmm11
compiles into
| 0000000000000000 <.text>:
| 0: f3 45 0f 7e db movq %xmm11,%xmm11
| 5: f3 0f 7e db movq %xmm3,%xmm3
| 9: f3 0f 7e db movq %xmm3,%xmm3
| d: f3 0f 7e db movq %xmm3,%xmm3
instead of proper
| 0000000000000000 <.text>:
| 0: f3 45 0f 7e db movq %xmm11,%xmm11
| 5: f3 45 0f 7e db movq %xmm11,%xmm11
| a: f3 45 0f 7e db movq %xmm11,%xmm11
| f: f3 45 0f 7e db movq %xmm11,%xmm11

longer force an index register.

[nosplit eax] has been encoded as [eax*1+0] since 0.98.34.
But this seems like unexpected behavior.
So only when a register is multiplied, that will be treated
as an index. ([nosplit eax*1] -> [eax*1+0])
Document is updated accordingly.

[nosplit eax+eax] was encoded [eax*2] previously but
this seems against the user's intention.
So in this case, nosplit is ignored now and [eax+eax] will be
generated.

In mib operands, users' intention should be preserved.
e.g.) [eax + eax*1] and [eax*2] must be distinguished and encoded differently.
So a new EA flag EAF_MIB for mib operands is added.
And a new EA hint EAH_SUMMED for the case of [eax+eax*4] being parsed
as [eax*5] is also added.
NOSPLIT specifier does not have an effect in mib, so [nosplit eax + eax*1]
will be encoded as [eax, eax] rather than [eax*2] as in a regular EA.

Added bnd warning and nobnd prefix. DEFAULT directive section
has got more description about BND-related settings.
Signed-off-by: Jin Kyu Song <jin.kyu.song@intel.com>

bnd and nobnd prifixes can be used for each instruction line to
direct whether bnd registers should be preserved or not.
And those are also added as options for DEFAULT directive.
Once bnd is set with default, DEFAULT BND, all bnd-prefix
available instructions are prefixed with bnd. To override it,
nobnd prefix can be used.
In the other way, DEFAULT NOBND can disable DEFAULT BND and
have nasm encode in the normal way.

In ndisasm, the priority follows the order of instructions in insns.dat.
Other iflags could affect this mechanism when a proper instruction form
had a higher iflag bit set.
The preferred mask bits are now limited to vendor flags (Cyrix and AMD)
and other flags do not affect disassembler any more.
