Local.cpp updated: 1.59 -> 1.60
SimplifyCFG.cpp updated: 1.103 -> 1.104

Log message:

For PR950: http://llvm.org/PR950 :
This patch converts the old SHR instruction into two instructions, 
AShr (Arithmetic) and LShr (Logical). The Shr instructions now are not
dependent on the sign of their operands.
