This commit defines subtarget feature strict-align and uses it instead of cl::opt -arm-strict-align to decide whether strict alignment should be forced. Also, remove the logic that was checking the OS and architecture as clang is now responsible for setting strict-align based on the command line options specified and the target architecute and OS. rdar://problem/21529937 http://reviews.llvm.org/D11470 llvm-svn: 243493
