There are a bunch of tests that use invalid memory acesses (on purpose)
to trigger a crash so that we can detect things are dumped correctly.
When we run under ASAN, it catches those accesses and the breaks the
testing flow.
For now, use the existing ADDRESS_SANITIZER symbol to disable more tests.
Ideally we'd use a compile-time attribute to disable ASAN on a few funcs,
but that seems to be broken atm.

If you try to process a file using a 32bit build that is larger than
2GiB in size, the linux kernel will reject things:
$ strace -eopen dump_syms ./chrome ./ > chrome.sym
...
open(".//chrome.debug", O_RDONLY) = -1 EOVERFLOW (Value too large for defined data type)
So let's use the existing autoconf macro to check for and enable support
as need be.
We have to shift the existing m32 logic up to before we start doing
feature test macros though otherwise a simple configure won't work:
$ ./configure --enable-m32
This is because it first tests LFS and such w/out the -m32 flags.

TEST=`./configure --enable-m32 && make && make check` passes

For CPUs that don't support the MMX instruction set, such pre-Pentium III or industrial x86 embedded PCs, the minidump fails when it tries to retrieve MMX specific registers.
This patch adds MMX detection for that call.
Tested on Ubuntu 12.04 with i686, and on a custom Linux distro on a Vortex86DX microcontroller.

It is incorrect to wrap close in HANDLE_EINTR on Linux.
Unnecessary #includes of eintr_wrapper.h are also removed. The variable naming
within the macro is also updated per Chromium r178174.
einter_wrapper.h contains a non-mechanical change. Mechanical changes were
generated by running:
sed -E -i '' \
-e 's/((=|if|return|CHECK|EXPECT|ASSERT).*)HANDLE(_EINTR\(.*close)/\1IGNORE\3/' \

The std::string dumpFilename already contains the full pathname to the dump file. Appending it to the dumpDirAsNSString creates a string with the path portion duplicated, e.g.:

SIGABRT can be generated internally, usually by calling abort(),
or externally by another process. When the signal is generated
by the kernel, info->si_pid is 0 and the signal is treated in the
same way as an exception (SIGSEGV, etc.), but the assumption
that the exception happens again upon return from the handler
is wrong, so we must have a special case for this.

.raSearchStart in the cases where there are alignment operators in
the program string.
If alignment operators are found in the program string, the current
value of %ebp must be valid and it is the only reliable data point
that can be used for getting to the previous frame. Previously, the
.raSearchStart calculation was based on %esp and when %esp is aligned
in the current frame (which is a lossy operation) the resulting
.raSearchStart cannot was incorrect. There is code that is trying to
work around this problem (scanning of up to 3 words for a return
address) which is unreliable and it doesn't work in many cases (e.g.
when the alignment is on a 64-byte boundary).
This fix is already deployed in Google and it was measured to reduce
the number of wrong stack traces (for Windows crashes) by 45%. No
regressions have been found so far.
Here is an example of an issue that was fixed by this change (where
register %esp is aligned on the 64-byte boundary and the workarounds
that we already had didn't work):

Apparently, as of the 10.8 SDK, Apple has quietly decided that the first
argument to NSLocalizedString is supposed to be usable as-is as a format
string, instead of simply being the key to obtain a usable format string.
The recent clang trunk enforces this, resulting in build breaks like
crash_report_sender.m:560:14: error: data argument not used by format string [-Werror,-Wformat-extra-args]
displayName];
^
Breaking the result of NSLocalizedString into a temporary NSString* is enough
to suppress the warning.

In my testing, ARM V8 object files and ARM V8 slices of universal binaries do
not contain debug_frame sections (at least at this time), and hence dump_syms
does not output CFI for ARM V8 even in the absence of the "-c" flag.

This patch fixes the build for Android on MIPS when
using the latest official Android NDK (r9):
- Update src/common/android/include/elf.h to add a missing
definition for SHT_MIPS_DWARF.
- Add src/common/android/include/sgidefs.h required by LSS
when compiling for MIPS.
- Update android/run-checks.sh to work properly with
the --abi=mips option. All tests were passed succesfully
with an emulator system image running Android 4.2.
- Update other Android-specific files.
