Reserved registers are unpredictable, and are treated as always live by machine
DCE.

Allocatable registers are never reserved, and can be used for virtual registers.

Unreserved, unallocatable registers can not be used for virtual registers, but
otherwise behave like a normal allocatable register. Most targets only have
the flag register in this set.

Make inline namespace not be transparent after all. The concept simply doesn't fit. Instead, special-case the few places where transparent contexts have the desired behavior for inline namespaces. Fixes a redeclaration issue in inline namespaces.

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.)

  - Cursor kinds for template parameters, with visitation logic
  - Visitation logic for template specialization types, qualified type

  - USR generation for function templates, template specialization
