Make references to Inits const everywhere.  This is the final step
before making them unique.

Remove all non-const iterators from Init classes.  This is another
step toward constifying Inits and ultimately turning them into
FoldingSetNodes.

Manage Inits in a FoldingSet.  This provides several benefits:

- Memory for Inits is properly managed

- Duplicate Inits are folded into Flyweights, saving memory

- It enforces const-correctness, protecting against certain classes
  of bugs

The above benefits allow Inits to be used in more contexts, which in
turn provides more dynamism to TableGen.  This enhanced capability
will be used by the AVX code generator to a fold common patterns
together.

attributes. These are requires for the new 'availability' attribute.

look safe in any case.
