Summary:
Failing tests just marked as UNSUPPORTED or XFAIL.
Some of them can be easily supported, but I'll do this in separate patches.

Remove the explicit i686 target that is completely duplicate to
the i386 target, with the latter being used more commonly.
1. The runtime built for i686 will be identical to the one built for
i386.
2. Supporting both -i386 and -i686 suffixes causes unnecessary confusion
on the clang end which has to expect either of them.
3. The checks are based on wrong assumption that __i686__ is defined for
all newer x86 CPUs. In fact, it is only declared when -march=i686 is
explicitly used. It is not available when a more specific (or newer)
-march is used.
Curious enough, if CFLAGS contain -march=i686, the runtime will be built
both for i386 and i686. For any other value, only i386 variant will be
built.

Breaks tests on i686/Linux due to missing clang driver support:
error: unsupported option '-fsanitize=leak' for target 'i386-unknown-linux-gnu'

People keep asking LSan to be available on 32 bit targets (e.g. https://github.com/google/sanitizers/issues/403)
despite the fact that false negative ratio might be huge (up to 85%). This happens for big real world applications
that may contain random binary data (e.g. browser), but for smaller apps situation is not so terrible and LSan still might be useful.
This patch adds initial support for x86 Linux (disabled by default), ARM32 is in TODO list.
We used this patch (well, ported to GCC) on our 32 bit mobile emulators and it worked pretty fine
thus I'm posting it here to initiate further discussion.

Summary: This is an initial setup in order to move some additional tests from Linux onto Posix.
I also moved decorate_proc_maps onto the Linux directory
Finally added msan's definition for "stable-runtime".
Only a test requires it, and its commit message (r248014) seems to imply
that AArch64 is problematic with MSan.

Summary:
This fixes duplicate test names in the test results, so:
PASS: SanitizerCommon-asan :: fopen_nullptr.c (304 of 431)
PASS: SanitizerCommon-asan :: fopen_nullptr.c (305 of 431)
is now:
PASS: SanitizerCommon-asan-i386-Linux :: fopen_nullptr.c (282 of 431)
PASS: SanitizerCommon-asan-x86_64-Linux :: fopen_nullptr.c (316 of 431)

Summary:
Teach all sanitizers to call abort() instead of _exit() after printing
an error report, if requested. This behavior is the default on Mac OS.

This follows the approach we use in ASan and UBSan lit tests to setup
tool options in a portable way, and to provide a nice way to specify
testsuite-wide defaults.

This is done by creating a named shared memory region, unlinking it
and setting up a private (i.e. copy-on-write) mapping of that instead
of a regular anonymous mapping. I've experimented with regular
(sparse) files, but they can not be scaled to the size of MSan shadow
mapping, at least on Linux/X86_64 and ext3 fs.
Controlled by a common flag, decorate_proc_maps, disabled by default.
This patch has a few shortcomings:
* not all mappings are annotated, especially in TSan.
* our handling of memset() of shadow via mmap() puts small anonymous
mappings inside larger named mappings, which looks ugly and can, in
theory, hit the mapping number limit.

We are interested in verifying that -gline-tables-only provides enough
debug information for verbose error reports and symbolized stack traces.
