kinst uses this function as well, but because it is not exported, it
implements its own copy of it. The patch also exposes the function to
userland, so programs that need to use dtrace_disx86() can use this
function instead of rolling their own copies.

Callers are specifying uint8_t anyway and this slightly reduces
dependencies on compatibility typedefs. No functional change intended.

These are fixed, so having upstream's version is not especially useful,
and the duplicated definitions make for confusing reading. No

Also reduce the diff between us and upstream: the input data model will
always be DATAMODEL_NATIVE because of a bug (p_model is never set but is
always initialized to 0), so we don't need to override the caller anyway.
This change is also necessary to support the pid provider for 32-bit
processes on amd64.

While the instructions were not included into the original instruction
set, their support can be indicated by a special feature bit.
For example:
CPU: AMD Phenom(tm) II X4 955 Processor (3214.71-MHz K8-class CPU)
...
AMD Features2=0x37ff<LAHF, ...>
Clang 3.8 uses lahf/sahf as a faster alternative to pushf/popf where
possible.

Since the upstream for cddl code is now illumos not sun, mechanically
convert all sun #ifdef's to illumos #ifdef's which have been used in all
newer code for some time.
Also do a manual pass to correct the use if #ifdef comments as per style(9)
as well as few uses of #if defined(__FreeBSD__) vs #ifndef illumos.

This includes decodes of recent Intel instructions, in particular
VT-x and related instructions. This allows the FBT provider to
locate the exit points of routines that include these new
instructions.
Illumos issues:

3415 Add isainfo support for f16c and rdrand
3416 Need disassembler support for rdrand and f16c
