Make sure no executable stack gets created.
Explanation by Matthias Schwarzott:
The linker will request an executable stack as soon as at least one
object file, that is linked in, wants an executable stack.
And the absence of the
.section .note.GNU-stack."",@progbits
is enough to tell the linker that an executable stack is needed.
So even an empty asm-file must at least contain this statement to not
force executable stacks on the whole executable.
* Define a helper macro MARK_STACK_NO_EXEC that disables the
executable stack.
* Instantiate this macro unconditionally at the end of each asm file.
Patch by Matthias Schwarzott <zzam@gentoo.org>.

Last optimisation for the day: change VG_(stats__n_xindirs) in such a
way that the fast-path through VG_(disp_cp_xindir) only has to
increment a 32 bit counter, saving memory bandwidth on 32 bit
platforms compared to a 64-bit inc. The overall numbers of XIndirs
can still be 64 bit though.

This commit merges the BUILD_TWEAKS branch onto the trunk. It has the
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.

Redo the dispatcher's fast-cache mechanism (VG_(tt_fast) et al) to be
more cache friendly. This changes the mechanism from being a table of
pointers to (guest address, translated code pairs) to being a table of
pairs (guest address, pointer to translated code). The effect ranges
from zero up to about 20% performance improvement on memcheck, the
biggest effects being seen for programs which jump around a large
number of blocks of code and whose data set does not fit in L2.

- Track vex r1494 (x86/amd64 change of conventions for getting
to translations and back to dispatcher, and also different arg
passing conventions to LibVEX_Translate).
- Rewrite x86 dispatcher to not increment the profiling counters
unless requested by the user. This dramatically reduces the
D1 miss rate and gives considerable performance improvement
on x86. Also, restructure and add comments to dispatch-x86-linux.S
to make it much easier to follow (imo).
