Changes in directory llvm/lib/Target/PowerPC:

PPC32CodeEmitter.cpp updated: 1.25 -> 1.26
---
Log message:

There is not a 1-1 mappign between llvm blocks and PPC blocks, do not use
LLVM blocks as the keys for the branch rewriter.  This fixes treeadd and
many other programs with the JIT.

Diffs of the changes:  (+4 -5)
