Chandler Carruth 91d19d8e93 Sort the #include lines for utils/... 
I've tried to find main moudle headers where possible, but the TableGen
stuff may warrant someone else looking at it.

Joerg Sonnenberger 7090937330 Don't use stack unwinding to provide the location information for 
SetTheory, but pass down the location explicitly.

David Greene 1aa0e3e118 [AVX] Constify Inits 
Make references to Inits const everywhere.  This is the final step
before making them unique.

David Greene 9908c17666 struct Init -> class Init 
Rename struct Init to class Init for consistency and in preparation
for making Init a FoldingSetNode.

David Greene af973b4f36 [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.

Jakob Stoklund Olesen fc205a5694 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)>;
