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.

Fix ARM bswap16.ll test on Windows

Windows on ARM only supports thumb mode execution, so we have to
explicitly pick some non-Windows OS to test ARM mode codegen.

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.
