[Chris Lattner]

Changes in directory llvm/lib/Target/PowerPC:

PPCISelLowering.cpp updated: 1.200 -> 1.201
---
Log message:

Fix miscompilation of float vector returns.  Compile code to this:

_func:
        vsldoi v2, v3, v2, 12
        vsldoi v2, v2, v2, 4
        blr

instead of:

_func:
        vsldoi v2, v3, v2, 12
        vsldoi v2, v2, v2, 4
***     vor f1, v2, v2
        blr
