the changes to do with reading and using ELF and DWARF3 info.
This breaks all targets except amd64-linux and x86-linux.

snapshots on ppc32-linux in the presence of functions subject to
leaf-function optimisations.
At the same time, simplify the stack unwinding logic by basically
implementing it separately for each target. Having a single piece of
logic for amd64 and x86 was tenable, but merging ppc32 into it is too
confusing. So now there is an x86/amd64 unwinder and a ppc32
unwinder.
This requires plumbing a link-register value into
VG_(get_StackTrace2), and that in turn requires passing it around
several other stack-trace-related functions. Hence 7 changed files.

As part of this, killed the VG_STRINGIFY macro, which was used to expand
out names like "VG_(foo)" and "vgPlain_foo" in assertion failure
messages. This is good since we actually want the "VG_(foo)" form used
in these messages.
