DeltaAlgorithm: Tweak split to split by first/second half instead of even/odd, since adjacent changes are more likely to be related.

ADT: Add DAGDeltaAlgorithm, which is a DAG minimization algorithm built on top of the standard 'delta debugging' algorithm.
 - This can give substantial speedups in the delta process for inputs we can construct dependency information for.

Refine BuiltinsARM.def types a bit, we should do a better job of this to save some c++ code in CGBuiltins.

- change isShuffleMaskLegal to show that all shuffles with 32-bit and 64-bit
  elements are legal
- the Neon shuffle instructions do not support 64-bit elements, but we were
  not checking for that before lowering shuffles to use them
- remove some 64-bit element vduplane patterns that are no longer needed

scrounging through SCEVUnknown contents and SCEVNAryExpr operands;
instead just do a simple deterministic comparison of the precomputed
hash data.

Also, since this is more precise, it eliminates the need for the slow
N^2 duplicate detection code.

Partial specialization was not checking the callsite to make sure it was using the same constants as the specialization, leading to calls to the wrong specialization.  Patch by Takumi Nakamura\!
