02d711b93e - Start moving target-dependent nodes that could be represented by an 
instruction sequence and cannot ordinarily be simplified by DAGcombine
  into the various target description files or SPUDAGToDAGISel.cpp.

  This makes some 64-bit operations legal.

- Eliminate target-dependent ISD enums.

- Update tests.

045a14503f CellSPU: 
(a) Slight rethink on i64 zero/sign/any extend code - use a shuffle to
    directly zero-extend i32 to i64, but use rotates and shifts for
    sign extension. Also ensure unified register consistency.
(b) Add new test harness for i64 operations: i64ops.ll
