GVN-hoist: limit hoisting depth (PR28670) This patch adds an option to specify the maximum depth in a BB at which to consider hoisting instructions. Hoisting instructions from a deeper level is not profitable as it increases register pressure and compilation time. Differential Revision: https://reviews.llvm.org/D22772 llvm-svn: 276713
