eedadc5fb3 get_abit_and_vbyte/get_abit can be a significant bottleneck when 
painting/checking huge numbers of bytes resulting from client check
requests.  Inlining them helps significantly.

c2a48e3498 This causes problems on setups where ld.so is mapped at just over 1M: 
it zeroes out that area (as a result of one of the mmaps) and the
program consequently goes into an infinite loop.  Change the map sizes
to just one page to avoid that.

5163ea2aed * Track introduction of IR ternary primops and rounding modes, at least as 
to the extent needed to make ppc32 work.

* As a result, remove the replacements for glibc's floor/ceil fns on 
  ppc32/64, since vex can now correctly simulate the real ones.

6af183ac21 Changes to make function wrapping work better on ppc64-linux: 
- when recording the non-redirected address in guest_NRADDR, also
  snapshot the current R2 value, as that will be needed to run the
  original safely

- As a consequence, the original-function information extracted by
  VALGRIND_GET_ORIG_FN is different on ppc64-linux (2 words) from
  all other platforms (1 word).  So change the type of it from
  void* to a new type OrigFn which can be defined differently for
  each platform.

- Change the CALL_FN_* macros for ppc64-linux to save/restore
  R2 values appropriately.

- ppc64-linux: detect overflow/underflow of the redirect stack
  and bring Valgrind to a halt if this happens

- Update VG_CLREQ_SZB for ppc32/64 (was out of date).

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).
