This branch adds proper support for atomic instructions, proper in the
sense that the atomicity is preserved through the compilation
pipeline, and thus in the instrumented code.
These changes track the IR changes added by vex r1901. They primarily
update the instrumentation functions in all tools to handle the
changes, with the exception of exp-ptrcheck, which needs some further
work in order to be able to run threaded code.

following improvements:
- Arch/OS/platform-specific files are now included/excluded via the
preprocessor, rather than via the build system. This is more consistent
(we use the pre-processor for small arch/OS/platform-specific chunks
within files) and makes the build system much simpler, as the sources for
all programs are the same on all platforms.
- Vast amounts of cut+paste Makefile.am code has been factored out. If a
new platform is implemented, you need to add 11 extra Makefile.am lines.
Previously it was over 100 lines.
- Vex has been autotoolised. Dependency checking now works in Vex (no more
incomplete builds). Parallel builds now also work. --with-vex no longer
works; it's little use and a pain to support. VEX/Makefile is still in
the Vex repository and gets overwritten at configure-time; it should
probably be renamed Makefile-gcc to avoid possible problems, such as
accidentally committing a generated Makefile. There's a bunch of hacky
copying to deal with the fact that autotools don't handle same-named files
in different directories. Julian plans to rename the files to avoid this
problem.
- Various small Makefile.am things have been made more standard automake
style, eg. the use of pkginclude/pkglib prefixes instead of rolling our
own.
- The existing five top-level Makefile.am include files have been
consolidated into three.
- Most Makefile.am files now are structured more clearly, with comment
headers separating sections, declarations relating to the same things next
to each other, better spacing and layout, etc.
- Removed the unused exp-ptrcheck/tests/x86 directory.
- Renamed some XML files.
- Factored out some duplicated dSYM handling code.
- Split auxprogs/ into auxprogs/ and mpi/, which allowed the resulting
Makefile.am files to be much more standard.
- Cleaned up m_coredump by merging a bunch of files that had been
overzealously separated.
The net result is 630 fewer lines of Makefile.am code, or 897 if you exclude
the added Makefile.vex.am, or 997 once the hacky file copying for Vex is
removed. And the build system is much simpler.

into the function DRD_(thread_new_segment_and_combine_vc)() because
before DRD_(thread_combine_vc_sync)() was called the function
DRD_(thread_new_segment)() was always called.

- Fixed memory allocation counters.
- Client memory is now freed in the realloc() wrapper in all cases where
it should be freed.

thread destroys and reinitializes a semaphore another thread is
waiting on but print an error message instead.
- Behavior change: always decrement 'value', even if this makes value
negative.
- Updated expected output files.

libgomp ABI has changed. Two new functions have been added, namely
gomp_team_barrier_wait() and gomp_team_barrier_wake(). The simplest way
to support all libgomp functions is by disabling the libgomp intercepts.
This fixes bug #195169.

- Replaced tempnam() by mkdtemp() / mkstemp() because gcc emits a warning
about the former.

right #define to test for, _APPLE_ is, but defined(VGO_darwin) is better
again. But even if that is fixed, there are still other problems.
So this commit just disables building of that test for Darwin.
