- A new monitor command 'xb <addr> <len>' shows the validity bits
of <len> bytes at <addr>. Below the validity bits, the byte
values are shown using a layout similar to the GDB command
'x /<len>xb <addr>'. The monitor command 'xb' is easier to use
(in particular on little endian computers) when you need to associate
byte data value with their corresponding validity bits.

inline functions. There is no command line flag so suppress that particular
warnings. So let's suppress all warnings for this testcase.

uninitialised. Perhaps an incorrect clobber or a compiler bug?
Anyhow, initialising the variable will do the trick.

It looks like the standard says that
#define __STDC_FORMAT_MACROS
is needed in c++ in order to have PRIxPTR defined.
At least on gcc110 g++ 4.7.2, leak_cpp_interior.cpp
was not compiling.

The patch was submitted by Will Schmidt (will_schmidt@vnet.ibm.com).
Update all vgtest files to reference the new capability check helper.
This includes a few adjustments to ensure the test is checking for
the specific capability. I.e. isa_2_07 is a requirement for htm, but
does not indicate htm support is actually present.

Also, add better sectioning with comment lines, as this part of the code
was getting hard to follow.

The new script (tests/check_ppc64_auxv_cap) in the first patch was
written for the bash shell. I was told by fkrohm that there was an
issue with bash sometime ago and the decision was to use sh instead.
sh maps to bash on a lot of systems but on some it maps to dash. The
script is not compatible with dash.
In retesting the second patch with a fresh svn pull, I found that I
forgot to do the svn add for the new script file. Which causes the
regression test to fail with the second patch applied.
So, I have decided it will be best to just back out patch 1 and 2 for now.
I will fix the script and do this again.

Update all vgtest files to reference the new capability check helper.

The interesting part is the demangled backtrace in the error message.
Suppress the memory allocation/blocks summary which can differ slightly
depending on the underlying arch/libs.

Fix multipleinheritance heuristic for ppc64LE (leak_cpp_interior test).
Adjust the PPC64 #ifdiffery to indicate that ppc64BE uses a thunk table,
but ppc64LE (in particular, the ELF ABIV2) does not. In this case, thunk
table == function descriptors.

Add a suppression to handle a "Jump to the invalid address..." message
that gets generated on power. This is a variation of the existing
suppressions.
While here, I also updated the "prog:" line in the vgtest file to reference
the supp_unknown executable, versus the badjump executable. They share the
same source code, so I think this is effectively cosmetic.

Adjust the badjump2 test for ppc64le/ABIV2. Under the ABIV2 there
is no function descriptor, so the fn[] setup does not apply.
This fixes the badjump2 test failure as seen on ppc64le.

when the size is known in advance.
3 places identified where this function can be used trivially.
The result is a reduction of 'realloc' operations in core
arena, and a small reduction in ttaux arena
(it is the nr of operations that decreases, the memory usage itself
stays the same (ignoring some 'rounding' effects).
E.g. for perf/bigcode 0, we change from
core 1085742/ 216745904 totalloc-blocks/bytes, 1085733 searches
ttaux 5348/ 6732560 totalloc-blocks/bytes, 5326 searches
to
core 712666/ 190998592 totalloc-blocks/bytes, 712657 searches
ttaux 5319/ 6731808 totalloc-blocks/bytes, 5296 searches
For bz2, we switch from
core 50285/ 32383664 totalloc-blocks/bytes, 50256 searches
ttaux 670/ 245160 totalloc-blocks/bytes, 669 searches
to
core 32564/ 29971984 totalloc-blocks/bytes, 32535 searches
ttaux 605/ 243280 totalloc-blocks/bytes, 604 searches
Performance wise, on amd64, this improves memcheck performance
on perf tests by 0.0, 0.1 or 0.2 seconds depending on the test.

What this does is to make sure that the initial client data segment
is marked as unaddressable. This is consistent with the behaviour of
brk when the data segment is shrunk. The "freed" memory is marked
as unaddressable.
Special tweaks were needed for s390 which was returning early from
the funtion to avoid sloppy register definedness initialisation.
