- Moved VG_MAX_REALREGS into x86/ part.
- Tweaked basic types so they're suitable for both 32-bit and 64-bit platforms.
Main change was to change 'Addr' to "unsigned long" which is the same size as
a pointer. Had to make a couple of minor changes to accommodate this.
Also, introduced 'UWord' and 'Word' types which will be necessary for making
code 64-bit clean.

- moved a lot of the baseBlock initialisation into x86/, including all the
VGOFF variables, and all the x86 asm helper functions.

Mackerras's work.
- introduced arch-neutral macros for getting the instruction/frame/stack
pointers.
- renamed ExeContext.eips as ExeContext.ips
- renamed esp/ebp/eip to sp/fp/ip in several related files and arch-neutralised
various comments
- introduced arch-neutral macros for walking the stack

- Added include/x86/: contains tool_arch.h, Makefile.am, .cvsignore.
- Added coregrind/x86/state.c. Contains some arch-specific code for dealing
with x86 registers -- eg. setting up the baseBlock, loading/saving the whole
register state. It is compiled into coregrind/x86/libarch.a and linked via
${VG_ARCH} with the core.
Relatedly, also added coregrind/x86/{core_arch.h,core_arch_asm.h}.
- Correspondingly abstracted the register state out of ThreadState. This
affected every place that touches registers, and there are a lot of them.
(Eventually all the register touching should be abstracted out in an
arch-neutral way, but not yet; one step at a time.)
- Added some declarations about register loading/saving functions to core.h;
all architectures will have to provide these functions.
- Rejigged the build system so that the arch-specific stuff is all done via
${VG_ARCH}, rather than naming e.g. x86/ directly. Appropriate -I arguments
are used so that all the headers are found, etc.
