The AttributeWithIndex class exposed the interior structure of the AttributeSet
class. That was gross. Remove it and all of the code that relied upon it.

This now uses the AttributeSet object instead of the Attribute /
AttributeWithIndex objects. It's fairly simple now. It goes through all of the
subsets before the one we're modifying, adds them to the new set. It then adds
the modified subset (with the requested attributes removed). And then adds the
rest of the subsets.

This adds support for LLVM to accept metadata that doesn't include a top level
lexical block in a function. Specifically LLVM couldn't handle this when there
were file changes relating to these blocks. I've updated a few test cases to
ensure other functionality (such as inlining) isn't affected by this change, but
haven't pervasively updated all the test cases.

The 'getSlot' function and its ilk allow introspection into the AttributeSet
class. However, that class should be opaque. Allow access through accessor
methods instead.

This adds an !add(a, b) operator to tablegen; this will be used
to cleanup the PPC register definitions.

Maintain separate per-node and per-tree book-keeping.
Track all instructions above a DAG node including nested subtrees.
Seperately track instructions within a subtree.
Record subtree parents.

Allow the strategy to select SchedDFS. Allow the results of SchedDFS
to affect initialization of the scheduler state.

This is mostly refactoring, along with adding an instruction count
within the subtrees and ensuring we only look at data edges.

if the vector is not empty. This will ensure that calls to these functions
will reference elements in the vector.

Allow schedulers to order DAG edges by critical path. This makes
DFS-based heuristics more stable and effective.

This is a helper class for the AttributeSetImpl class. It holds a set of
attributes that apply to a single element: function, return type, or
parameter.
These are uniqued.
