Louis Gerbarg 9cec62a27f Add support bswap16 to/from memory compiling to rev16 on ARM/Thumb
The current patterns for REV16 misses mostn __builtin_bswap16() due to
legalization promoting the operands to from load/stores toi32s and then
truncing/extending them. This patch adds new patterns that catch the resultant
DAGs and codegens them to rev16 instructions. Tests included.
