Find cold blocks based on profile information (or optionally with static analysis). Forward propagate profile information to all cold-blocks. Outline a cold region. Set calling conv and prof hint for the callsite of the outlined function. Worked in collaboration with: Sebastian Pop <s.pop@samsung.com> Differential Revision: https://reviews.llvm.org/D50658 llvm-svn: 341669
