Nicholas Nethercote 18355ff96b Arch-abstraction:
- 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.
