pairs for 32-bit immediates. This change is needed to avoid emitting movt/movw pairs when doing LTO and do so on a per-function basis. Out-of-tree projects currently using cl::opt option -arm-use-movt=0 or false to avoid emitting movt/movw pairs should make changes to add subtarget feature "+no-movt" (see the changes made to clang in r242368). rdar://problem/21529937 Differential Revision: http://reviews.llvm.org/D11026 llvm-svn: 242369
