* print the output 64-bit results in most-to-least-significant
lane format
* change the memory values used in these tests to ones which
are reliably able to detect confusion of 8-bit lanes. The
previous values couldn't to that reliable. This change causes
the diff to be huge because the stdout.exp changes a lot.

Reading header length and values in external line info was incorrect at
some places as it used offsets based on dw64 that came from .debug_info.
Instead, offsets should be calculated based on is64 from .debug_line.
This issue surfaced in MIPS64 port, and it was discussed at:
https://bugs.kde.org/show_bug.cgi?id=313267#c20

it easier to sync with stderr output. Also, add some more helpful
data for testing Neon loads/stores.

Explicitly test together with -static -nodefaultlibs -nostartfiles to mimic
what the tools linking script does. At least on s390 the test might fail for
a non-static AC_LINK, while it does work when using those other flags too.

Bug #305513. We should only read the first DIE of a compilation unit.
Each compilation unit header is followed by a single DW_TAG_compile_unit
(or DW_TAG_partial_unit, but those aren't important here) and its children.
There is no reason to read any of the children at this point. If the first
DIE isn't a DW_TAG_compile_unit we are done, none of the child DIEs will
provide any useful information.

Bug #305513 contained a patch for some extra robustness checks. But
the real cause of crashing in the read_unitinfo_dwarf2 DWARF reader
seemed to have been this issue where DWARF version 2 DWZ partial_units
were read and DW_FORM_ref_addr had an unexpected size. This combination
is rare. DWARF version 4 is the current default version of GCC.

The replacement functions are running on the simulated CPU.
The code on the simulated CPU does not necessarily use
all arguments. E.g. args can be ignored and/or only given
to a NON SIMD call.
The definedness of such 'unused' arguments will not be verified
by memcheck.
A call to 'trigger_memcheck_error_if_undefined' allows
memcheck to detect such errors for the otherwise unused args.
Apart of allowing memcheck to detect an error, the function
trigger_memcheck_error_if_undefined has no effect and
has a minimal cost for other tools replacing malloc functions.
(suggestion of the 'no operation check' from Julian).
tested on f12/x86, debian6/amd64, f18/ppc64
Note that some Darwin specific code has been modified
in coregrind/m_replace_malloc/vg_replace_malloc.c.
(Some of) this code has not been compiled (no access to a
Darwin system). The code changed is trivial, so there is
some chance it will compile and even maybe work.
Added a new test verifying that various malloc related
functions undefined args are triggering an error in memcheck.

MIPS uses different values for socket types.
This is protected by ARCH_HAS_SOCKET_TYPES in Linux kernel and we introduce
it here too. This is important for log-socket feature, and it resolves the
issue reported in https://bugs.kde.org/show_bug.cgi?id=313267#c21.

Enable wrappers on mips64 for the following calls:
- dup3
- accept4
- epoll_create1
- timerfd_settime
- newfstatat
Also, allow additional flock64 values in sys_fcntl for mips64.
git-svn-id: svn://svn.valgrind.org/valgrind/trunk@13358
Add mips64-le implementation of:
- atomic_add_8bit
- atomic_add_16bit
- atomic_add_32bit
- atomic_add_64bit
- do_acasW
Minor fixes for mips32 implementations are included as well.
These functions are needed to execute atomic_incs and annotate_hbefore
tests on mips64le.

memcheck/tests/vbit-test fails with unknown opcode after introduction

(problem reported in bug 307082, comment 8).
Solution applied is similar to what is in 307082 patch
(i.e. do not destroy the internal helgrind var if nWaiters > 0).
But also do not remove it from the FM.
+ add a test case (re-using the drd test case)

* when SEGV trapped, report the main thread size as an unsigned size_t
* Similar for memcheck overlap errors
For example, for the 2 calls:
memcpy(&a, &a, 2147483648UL);
memcpy(&a, &a, -1); // silently accepted by gcc 4.4.4 -Wall
// while the 3rd arg is supposed to be a size_t
we now obtain (on a 32 bit system)
Source and destination overlap in memcpy(0xbe97113f, 0xbe97113f, 2147483648)
Source and destination overlap in memcpy(0xbef6d13f, 0xbef6d13f, 4294967295)
instead of
Source and destination overlap in memcpy(0xbe8e012f, 0xbe8e012f, -2147483648)
Source and destination overlap in memcpy(0xbe8e012f, 0xbe8e012f, -1)
Do not ask me why
memcpy(&a, &a, -1);
is supposed to be accepted/acceptable/valid code.
