[ARM] Pass subtarget feature "+strict-align".
This commit changes the driver to save subtarget feature "+strict-align" to the
IR instead of using backend option "arm-strict-align". This is needed for LTO.
Also, move the logic in ARM backend that was deciding whether strict alignment
should be forced to the front-end.
