possible fix

The attached patch hooks into mapping_state() to mark the alignment requirement
on the current output section whenever we start emitting instructions.

It might be safer to make the alignment 4 for Thumb code as well as ARM code;
the current patch gives Thumb code an alignment of 2 bytes, based on the
principles that (a) this makes the current situation no worse, and (b) all
realistic situations where a Thumb code section requires 4-byte alignment will
involve an explicit .align or literal pool somewhere, so we don't need to
worry.
