template. Such cursors occur, for example, in template specialization
types such as vector<int>. Note that we do not handle the
super-interesting case where the template name is unresolved, e.g.,
within a template.

I have not been able to find a way to test each in isolation, for a few reasons:
1) The ability to look-through non-i1 BinaryOperator's requires the ability to look through non-constant
ICmps in order for it to ever trigger.
2) The ability to do LVI-powered PHI value determination only matters in cases that ProcessBranchOnPHI
can't handle. Since it already handles all the cases without other instructions in the def-use chain
between the PHI and the branch, it requires the ability to look through ICmps and/or BinaryOperators
as well.

1. Allocate them in the entry block of the function to enable function-wide
re-use. The instructions to create them should be re-materializable, so
there shouldn't be additional cost compared to creating them local
to the basic blocks where they are used.
2. Collect all of the frame index references for the function and sort them
by the local offset referenced. Iterate over the sorted list to
allocate the virtual base registers. This enables creation of base
registers optimized for positive-offset access of frame references.
(Note: This may be appropriate to later be a target hook to do the
sorting in a target appropriate manner. For now it's done here for
simplicity.)

to delegate the building of binaries to a sys.platform-sepcific plugin.
Modified the dotest.py test driver to add the "plugins" directory to the
PYTHONPATH as well.
darwin.py is the Mac OS X plugin module.

libclang. This includes:
- Cursor kind for function templates, with visitation logic
- Cursor kinds for template parameters, with visitation logic
- Visitation logic for template specialization types, qualified type
locations
- USR generation for function templates, template specialization
types, template parameter types.
Also happens to fix PR7804, which I tripped across while testing.

conversion functions. This introduces new cursor kinds for these three
C++ entities, and reworks visitation of function declarations so that
we get type-source information for the names.

any more. I plan to reimplement alloca promotion using SSAUpdater later.
It looks like Bill's URoR logic really always needs domtree, so the pass
now always asks for domtree info.

two are weak, we make them thunks to a new strong function) so don't iterate
through the function list as we're modifying it.
Also add back the outermost loop which got removed during the cleanups.

This actually exposed an infinite recursion bug in ComputeValueKnownInPredecessors which theoretically already existed (in JumpThreading's
handling of and/or of i1's), but never manifested before. This patch adds a tracking set to prevent this case.

getMagicNumber was treating the _binary_ data it read in as a
null terminated string. This resulted in the std::string
calculating the length, and causing an assert in other code that
assumed that the length it passed was the same as the length of
the string it would get back.
