5207bf2177 Lower mem-ops to unaligned i32/i16 load/stores on ARM where supported. 
Add support for trimming constants to GetDemandedBits. This fixes some funky
constant generation that occurs when stores are expanded for targets that don't
support unaligned stores natively.

75757f9fd1 Make sure short memsets on ARM lower to stores, even when optimizing for size.
