Small cleanup of MachineLICM.cpp Specifically: - Calculate the loop pre-header once at the stat of HoistOutOfLoop, so: - We don't-DFS walk the MachineDomTree if we aren't going to do anything - Don't call getCurPreheader for each Scope - Don't needlessly use a do-while loop - Use early exit for Scopes.size() == 0 No functional changes intended. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@228350 91177308-0d34-0410-b5e6-96231b3b80d8
