[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.

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.

Use -Wl,defs when linking.
ELF linkers by default allow shared libraries to contain undefined references

On COFF and MachO, that is not the case.
This creates a situation where a .so might build on an ELF system, but the build
of the corresponding .dylib or .dll will fail.
