system that allows multiple copies of valgrind to be built so that we
can build both x86 and amd64 versions of the tools on amd64 machines.
The launcher is then modified to look at the program being run and
decide which tool to use to run it.

changes from r4341 through r4787 inclusive). That branch is now dead.
Please do not commit anything else to it.
For the most part the merge was not troublesome. The main areas of
uncertainty are:
- build system: I had to import by hand Makefile.core-AM_CPPFLAGS.am
and include it in a couple of places. Building etc seems to still
work, but I haven't tried building the documentation.
- syscall wrappers: Following analysis by Greg & Nick, a whole lot of
stuff was moved from -generic to -linux after the branch was created.
I think that is satisfactorily glued back together now.
- Regtests: although this appears to work, no .out files appear, which
is strange, and makes it hard to diagnose regtest failures. In
particular memcheck/tests/x86/scalar.stderr.exp remains in a
conflicted state.
- amd64 is broken (slightly), and ppc32 will be unbuildable. I'll
attend to the former shortly.

malloc/free implementation, and m_replacemalloc with the stuff for the tools
that replace malloc with their own version. Previously these two areas of
functionality were mixed up somewhat.

- In Cachegrind, abstract out x86-specific use of CPUID to find cache
configuration. Required adding a cachegrind/x86/ directory, and fiddling
a bit with the build system.

- 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.
