4e51dcae40 Converted all the remaining available separate fields in bxInstruction_c
to bitfields.  bxInstruction_c is now 24 bytes, including 4 for
the memory addr resolution function pointer, and 4 for the
execution function pointer (16 + 4 + 4).

Coded more accessors, to abstract access from most code.

6723ca9bf4 Moved more separate fields in the bxInstruction_c into bitfields
with accessors.  Had to touch a number of files to update the
access using the new accessors.

Moved rm_addr to the CPU structure, to slim down bxInstruction_c
and to prevent future instruction caching from getting sprayed
with writes to individual rm_addr fields.  There only needs to
be one.  Though need to deal with instructions which have
static non-modrm addresses, but which are using rm_addr since
that will change.

bxInstruction_c is down to about 40 bytes now.  Trying to
get down to 24 bytes.

07b0df2a8a Updated accessing of modrm/sib addressing information to
use accessors.  This lets me work on compressing the
size of fetch-decode structure (now called bxInstruction_c).

I've reduced it down to about 76 bytes.  We should be able
to do much better soon.  I needed the abstraction of the
accessors, so I have a lot of freedom to re-arrange things
without making massive future changes.

Lost a few percent of performance in these mods, but my
main focus was to get the abstraction.

80dd7a07ec Removed references to building libextdb.a. It doesn't seem to
be used at all, and Peter didn't want it.  "extdb.o" is compiled
into libcpu.a, if configured for it.

Removed a few #warnings for x86-64 compile, based on Peter's
line-item comments regarding the warnings I inserted during
the port/merge.

f05d453b6c Moved 64-bit only files from cpu64 to cpu and modified the Makefiles
accordingly.  These files cause no conflicts at all, since they
are not used in 32-bit compiles.
