[X86][SSE] Added support for SSE3 lane duplication shuffle instructions
This patch adds shuffle matching for the SSE3 MOVDDUP, MOVSLDUP and MOVSHDUP instructions. The big use of these being that they avoid many single source shuffles from needing to use (pre-AVX) dual source instructions such as SHUFPD/SHUFPS: causing extra moves and preventing load folds.
Adding these instructions uncovered an issue in XFormVExtractWithShuffleIntoLoad which crashed on single operand shuffle instructions (now fixed). It also involved fixing getTargetShuffleMask to correctly identify theses instructions as unary shuffles.

[PM] Refactor the InstCombiner interface to use an external worklist.
Because in its primary function pass the combiner is run repeatedly over
the same function until doing so produces no changes, it is essentially
to not re-allocate the worklist. However, as a utility, the more common
pattern would be to put a limited set of instructions in the worklist
rather than the entire function body. That is also the more likely
pattern when used by the new pass manager.
The result is a very light weight combiner that does the visiting with
a separable worklist. This can then be wrapped up in a helper function
for users that want a combiner utility, or as I have here it can be
wrapped up in a pass which manages the iterations used when combining an
entire function's instructions.
Hopefully this removes some of the worst of the interface warts that
became apparant with the last patch here. However, there is clearly more
work. I've again left some FIXMEs for the most egregious. The ones that
stick out to me are the exposure of the worklist and IR builder as
public members, and the use of pointers rather than references. However,
fixing these is likely to be much more mechanical and less interesting
so I didn't want to touch them in this patch.

tsan: don't unroll memory access loop in debug mode
MemoryAccess function consumes ~4K of stack in debug mode,
in significant part due to the unrolled loop.
And gtest gives only 4K of stack to death test
threads, which causes stack overflows in debug mode.

[PM] Replace an abuse of inheritance to override a single function with
a more direct approach: a type-erased glorified function pointer. Now we
can pass a function pointer into this for the easy case and we can even
pass a lambda into it in the interesting case in the instruction
combiner.
I'll be using this shortly to simplify the interfaces to InstCombiner,
but this helps pave the way and seems like a better design for the
libcall simplifier utility.

[sanitizer] First step toward supporting 42-bit AS on aarch64
aarch64-linux kernel has configurable 39, 42 or 47 bit virtual address
space. Most distros AFAIK use 42-bit VA right now, but there are also
39-bit VA users too. The ppc64 handling can be used for this just fine
and support all the 3 sizes.
There are other issues, like allocator32 not really being able to support
the larger addres spaces, and hardcoded 39-bit address space size in other
macros.

[sanitizer] Fix aarch64 sanitizer build with recent glibc
glibc recently changed ABI on aarch64-linux:
https://sourceware.org/git/?p=glibc.git;a=commit;h=
5c40c3bab2fddaca8cfe12d75944d1fef8adf1a4
Instead of having unsigned short mode; unsigned short __pad1; it now has
unsigned int mode; field in ipc_perm structure.
This patch allows to build against the recent glibc and disables the
ipc_perm.mode verification for older versions of glibc.
I think it shouldn't be a big deal even for older glibcs, I couldn't find
any place which would actually care about the exact mode field, rather than
the whole structure, appart from the CHECK_SIZE_AND_OFFSET macro.

The counter was assumed to be either zero or one, but obviously it

Fix some platform specific paths in TestSettings.py.
We were referring to hardcoded paths /bin/ls and /bin/cat. For
the purposes of this test, the actual value it's set to doesn't
matter, and it might as well be a non-existent path. All that
matters is that the before and after values have to match, and
that trailing whitespace is stripped. On Windows FileSpec
(correctly) converts /bin/ls to D:\bin\ls though, so the before
and after values won't match. So this patch just correctly builds
up a valid path in a platform-agnostic manner, and verifies that
it matches before and after the set.

[PM] Separate the InstCombiner from its pass.
This creates a small internal pass which runs the InstCombiner over
a function. This is the hard part of porting InstCombine to the new pass
manager, as at this point none of the code in InstCombine has access to
a Pass object any longer.
The resulting interface for the InstCombiner is pretty terrible. I'm not
planning on leaving it that way. The key thing missing is that we need
to separate the worklist from the combiner a touch more. Once that's
done, it should be possible for *any* part of LLVM to just create
a worklist with instructions, populate it, and then combine it until
empty. The pass will just be the (obvious and important) special case of
doing that for an entire function body.
For now, this is the first increment of factoring to make all of this
work.
