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.)

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.

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.

llvm-svn: 112595

Don't perform an extra traversal of the function just to do cleanup.  We can safely simplify instructions after each block has been processed without worrying about iterator invalidation.

More Chris-inspired JumpThreading fixes: use ConstantExpr to correctly constant-fold undef, and be more careful with its return value.
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.
