RFA: build i386-darwin

- Subject: RFA: build i386-darwin
Hi
currently gdb is the same when configured for i386-darwin or x86_64-darwin.
This is obviously wrong as without --enable-64-bit-bfd, i386-darwin won't
handle correctly 64 bit addresses and compilation will generate warnings.
In a effort to clean, I extracted amd64-darwin-tdep.[ch] from
i386-darwin-tdep.[ch].
However, there is still only i386-darwin-nat.c It contains a few #ifdef BFD64/
#endif almost like sparc-sol2-nat.c. This is not very beautiful but I wasn't
able to find a better method: creating an amd64-darwin-nat.c doesn't work
very well: it will duplicate most of i386 code (we can't really use the same
trick as done for linux) and it will need to link with both
i386-darwin-nat.c and amd64-darwin-nat.c which is never expected.
So I prefer to use #ifdef/#endif. Maybe later I will be able to find a better
solution.
Compiled on both i386/amd64 darwin, no regressions with amd64 with i386
compiler.
Tristan.

* i386-darwin-tdep.c (amd64_darwin_thread_state_reg_offset)
(amd64_darwin_thread_state_num_regs)
(amd64_darwin_sigcontext_addr, x86_darwin_init_abi_64): Moved to
amd64-darwin-tdep.c
(_initialize_i386_darwin_tdep): Remove 64 bits parts.
(darwin_dwarf_signal_frame_p): Make public.
* amd64-darwin-tdep.c: New file with most chunks from
i386-darwin-tdep.c
* i386-darwin-tdep.h: Add a prototype for darwin_dwarf_signal_frame_p.
(amd64_darwin_thread_state_reg_offset)
(amd64_darwin_thread_state_num_regs): Moved to amd64-darwin-tdep.h
* amd64-darwin-tdep.h: New file.
* i386-darwin-nat.c: Only includes amd64-nat.h and amd64-darwin-tdep.h
if BFD64 is defined.
(i386_darwin_fetch_inferior_registers): Add #ifdef BFD64/#endif around
64 bits parts.
(i386_darwin_store_inferior_registers): Ditto.
(darwin_set_sstep): Ditto.
(darwin_complete_target): Ditto.
(amd64_darwin_sstep_at_sigreturn): Ditto.
* configure.tgt: Create a separate entry for x86_64-*-darwin.
Add 64 bits support for i386-*-darwin if --enable-64-bit-bfd.
* Makefile.in (ALLDEPFILES): Add amd64-darwin-tdep.c, darwin-nat.c,
i386-darwin-tdep.c i386-darwin-nat.c
(ALL_64_TARGET_OBS): Add amd64-darwin-tdep.o
