87f080949b Implement the Expand action for binary vector operations to break the binop 
into elements and operate on each piece.  This allows generic vector integer
multiplies to work on PPC, though the generated code is horrible.

d9e4daabd2 Do not endian swap split vector loads. This fixes UnitTests/Vector/sumarray-dbl on PPC. 
Now all UnitTests/Vector/* tests pass on PPC.

8e1fcab2bc Scalarized vector stores need not be legal, e.g. if the vector element type 
needs to be promoted or expanded.  Relegalize the scalar store once created.
This fixes CodeGen/Generic/vector.ll:test1 on non-SSE x86 targets.

5fe1f54c17 Significantly improve handling of vectors that are live across basic blocks, 
handling cases where the vector elements need promotion, expansion, and when
the vector type itself needs to be decimated.

994d8e6bd4 For targets with FABS/FNEG support, lower copysign to an integer load,

462505fc5f Completely rewrite libcall insertion by the legalizer, providing the 
following handy-dandy properties:

1. it is always correct now
2. it is much faster than before
3. it is easier to understand

This implementation builds off of the recent simplifications of the
legalizer that made it single-pass instead of iterative.

This fixes JM/lencod, JM/ldecod, and
CodeGen/Generic/2006-02-12-InsertLibcall.ll (at least on PPC).
