Remove const qualifiers from Init references, per Chris' request.

f37dd02f77 [AVX] Constify Inits
Make references to Inits const everywhere.  This is the final step
before making them unique.

afd54269ab struct Init -> class Init
Rename struct Init to class Init for consistency and in preparation
for making Init a FoldingSetNode.

d568b3f552 Revert r134921, 134917, 134908 and 134907. They're causing failures
in multiple buildbots.

d4a9066c93 [AVX] Make Inits Foldable
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.

1de99829b6 Teach TableGen to evaluate DAG expressions as set operations.
A TableGen backend can define how certain classes can be expanded into
ordered sets of defs, typically by evaluating a specific field in the
record. The SetTheory class can then evaluate DAG expressions that refer
to these named sets.

A number of standard set and list operations are predefined, and the
backend can add more specialized operators if needed. The -print-sets
backend is used by SetTheory.td to provide examples.

This is intended to simplify how register classes are defined:

  def GR32_NOSP : RegisterClass<"X86", [i32], 32, (sub GR32, ESP)>;
