[llvm-commits] Optimize sign-extends and negative predicates in Hexagon

[Sirish Pande]

I have attached a patch that optimizes the sign extends and negative 
predicates in Hexagon. This is very specific to Hexagon, and it won't 
affect any other target.

This patch replaces the file HexagonOptimizeSZExtends.cpp with 
HexagonPeephole.cpp as it accomplishes more than optimizing sign extends.
