This commit is for Bugzilla 334384.  The Bugzilla contains patch 1 of 3
to add PPC64 LE support.  The other two patches can be found in Bugzillas
334834 and 334836.  The commit does not have a VEX commit associated with it.

POWER PC, add initial Little Endian support

The IBM POWER processor now supports both Big Endian and Little Endian.
This patch renames the #defines with the name ppc64 to ppc64be for the BE
specific code.  This patch adds the Little Endian #define ppc64le to the

Additionally, a few functions are renamed to remove BE from the name if the
function is used by BE and LE. Functions that are BE specific have BE put
in the name.

The goals of this patch is to make sure #defines, function names and
variables consistently use PPC64/ppc64 if it refers to BE and LE,
PPC64BE/ppc64be if it is specific to BE, PPC64LE/ppc64le if it is LE
specific.  The patch does not break the code for PPC64 Big Endian.

The test files memcheck/tests/atomic_incs.c, tests/power_insn_available.c
and tests/power_insn_available.c are also updated to the new #define
definition for PPC64 BE.

This commit is for Bugzilla 334834.  The Bugzilla contains patch 2 of 3
to add PPC64 LE support.  The other two patches can be found in Bugzillas
334384 and 334836.

POWER PC, add the functional Little Endian support, patch 2 

The IBM POWER processor now supports both Big Endian and Little Endian.
The ABI for Little Endian also changes.  Specifically, the function
descriptor is not used, the stack size changed, accessing the TOC
changed.  Functions now have a local and a global entry point.  Register
r2 contains the TOC for local calls and register r12 contains the TOC
for global calls.  This patch makes the functional changes to the
Valgrind tool.  The patch makes the changes needed for the
none/tests/ppc32 and none/tests/ppc64 Makefile.am.  A number of the
ppc specific tests have Endian dependencies that are not fixed in
this patch.  They are fixed in the next patch.

Per Julian's comments renamed coregrind/m_dispatch/dispatch-ppc64-linux.S
to coregrind/m_dispatch/dispatch-ppc64be-linux.S  Created new file for LE
coregrind/m_dispatch/dispatch-ppc64le-linux.S.  The same was done for
coregrind/m_syswrap/syscall-ppc-linux.S.

PP64 Little Endian test case fixes.

This patch adds new LE and BE expect files where needed.  In other
cases, the test was fixed to run correctly on LE and BE using based on
testing to see which platform is being used.

Where practical, the test cases have been changed so that the output
produced for BE	 and LE will be identical.  The test cases that require
a major rewrite to make the output identical for BE and LE simply
had an additional expect file added.
