eef723fbcc An extension of the previous commit: the vg_perf --tools option is so useful 
that I got rid of the "tools:" line in the .vg_perf files.

7a2f3512f4 Add a useful --tools option to vg_perf, which lets you override the "tools" 
line in the .vgperf files from the command line.

931e8921fd Just use the first two letters of the toolname as the abbreviation.

cb28dcdea2 Merge r6216: 
Fix all the places where gcc complains about casts from pointers
(presumably 64 bit) to integers of different size (in this case,
32-bit int).  This makes it compile cleanly on 64-bit AIX and also
means it doesn't crash :-)

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).

bf87ad4bb6 Attempt to make tinycc work on ppc32, by (1) getting rid of various 
x86 isms in tinycc.c, (2) giving it a fixed, preprocessed input file
to chew on, and (3) just compiling to a .o with no attempt to link.

49db1b68a8 First attempt at some performance tracking tools. Includes a script vg_perf 
(use "make perf" to run) that executes test programs and times their
slowdowns under various tools.  It works a lot like the vg_regtest script.
It's a bit rough around the edges -- eg. you can't currently directly
compare two different versions of Valgrind, which would be useful -- but it
is a good start.

There are currently two test programs in perf/.  More will be added as time
goes on.  This stuff will be built on so that performance changes can be
tracked over time.
