[Bug target/67745] [ARM] wrong alignments when __attribute__ ((optimize,target,align) is used

--- Comment #3 from chrbr at gcc dot gnu.org ---
another example that gives suboptimal alignment:

void
__attribute__ ((optimize("Os")))
foo()
{
}

compiled with -O2 -mthumb is aligned on 2^2 instead of 2^1. -Os should remove
padding here.
