83e447c886 Makefiles: Teach LLVM's recursive makefile descent to update objdir Makefiles if
they are out of date, instead of only testing if they exist.

039adfc699 DeltaAlgorithm: Tweak split to split by first/second half instead of even/odd, since adjacent changes are more likely to be related.

956f97134b 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.

20bda8100d Add more virtual memory to lit. The python in x86-64 fedora 13 needs it to run
the llvm tests :-(
It was failing with

d62b29412b Use realloc instead of malloc+memcpy when growing a POD SmallVector. A smart
realloc implementation can try to expand the allocated memory block in-place,
avoiding the copy.

9cf6656d4b Further changes for Neon vector shuffles:
- 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

65954b2eb4 Optimize ScalarEvolution's SCEVComplexityCompare predicate: don't go
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.

a96eaed21d Create new accessors to get arguments for call/invoke instructions. It breaks
encapsulation to force the users of these classes to know about the internal
data structure of the Operands structure. It also can lead to errors, like in
the MSIL writer.
