Move GlobalMerge from Transform to CodeGen. This patch is to move GlobalMerge pass from Transform/Scalar to CodeGen, because GlobalMerge depends on TargetMachine. In the mean time, the macro INITIALIZE_TM_PASS is also moved to CodeGen/Passes.h. With this fix we can avoid making libScalarOpts depend on libCodeGen. llvm-svn: 210951

AArch64: strengthen Darwin ABI alignment assumptions A global variable without an explicit alignment specified should be assumed to be ABI-aligned according to its type, like on other platforms. This allows us to use better memory operations when accessing it. rdar://18533701 llvm-svn: 223180
