Peter Collingbourne 84c287e33c Move TableGen's parser and entry point into a library 
This is the first step towards splitting LLVM and Clang's tblgen executables.

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

Eric Christopher 71520a867d Revert r134921, 134917, 134908 and 134907. They're causing failures 
in multiple buildbots.

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.
