991367c922 Merge in the COMPVBITS branch to the trunk. This is a big change to 
Memcheck, replacing the 9-bits-per-byte shadow memory representation to a
2-bits-per-byte representation (with possibly a little more on the side) by
taking advantage of the fact that extremely few memory bytes are partially
defined.

For the SPEC2k benchmarks with "test" inputs, this speeds up Memcheck by a
(geometric mean) factor of 1.20, and reduces the size of shadow memory by a
(geometric mean) factor of 4.26.

At the same time, Addrcheck is removed.  It hadn't worked for quite some
time, and with these improvements in Memcheck its raisons-d'etre have
shrivelled so much that it's not worth the effort to keep around.  Hooray!

Nb: this code hasn't been tested on PPC.  If things go wrong, look first in
the fast stack-handling functions (eg. mc_new_mem_stack_160,
MC_(helperc_MAKE_STACK_UNINIT)).

32f134b8c1 Somewhat rehash the biarch-build machinery so as to (1) formalise the 
distinction between primary and secondary build targets, and (2) make
it independent of the default behaviour of gcc (iow, what gcc does
when you specify neither -m32 nor -m64).

As a result, an out-of-the-box build on ppc64-linux now builds a
system which is basically for 64-bit PowerPC, but also has the ability
to run 32-bit ppc-linux binaries (exactly the same arrangement as you
get when building on amd64-linux).

There are various twists and turns.  multiple-architectures.txt is
updated all the gory details.

This will break amd64 builds until such time as
<tool>/tests/{amd64,x86}/Makefile.am are fixed up (shortly).

4d4bc5d1f6 fixed up ppc64 assembly with .opd sections 
do_syscall_for_client_WRK() needed a bigger stack to avoid the linkage area.

always use dot_prefix for label calls

not wrapping assembly with
.section ".text"
...
.previous
 - ppc64 doesn't like it... seems we can't 'stack' more than one section to pop off with .previous ?
