Print FS_MSR_BASE and GS_MSR_BASE to debug registers dump (requested in bug report [ 1406387 ] JMP instruction should display absolute address)
...
Fixed fetch mode mask initialization (bug report 1400027 Boundary instruction cache error for uninitialized memory)
For safety only - everytime when changing CS register update fetch mode mask.
Actually it need to be updated everytime when there is a chance for execute mode change or 16/32 bit mode change.

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.

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.

I merged the cpu/cpu.h and cpu64/cpu.h files as well as the
...
other header files. There no longer are any *.h files in cpu64/.
Had to make some changes to the *.cc files for dealing with
accesses to eip.
