[PATCH] ARM: Do not allow unaligned accesses when CONFIG_ALIGNMENT_TRAP

It is possible that -fconserve-stack is still valuable on ARM given that 
it is also used with -mno-unaligned-access for other things than 
structure packing on the stack, and therefore its merits can be debated 
independently from the alignment issue at hand.

Catalin said in his mail "I haven't tried with -mno-unaligned-access, I
suspect the variables on the stack would be aligned.".  So I don't think
we know enough to say whether -mno-unaligned-access avoids the stack
packing.
