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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@210951 91177308-0d34-0410-b5e6-96231b3b80d8

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 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@223180 91177308-0d34-0410-b5e6-96231b3b80d8
