arm: Add a W() macro for use in kernel assembler.

Browse source 
Some kernel assembly code uses a W macro to optionally add a .w to
instructions that need to be 32 bit thumb. The gnu assembler doesn't seem to
need the .w and won't assemble if it's provided.

BUG=None
TEST=Built for snow with the kernel's implementation of memmove (which uses
W()), and used memmove successfully when loading from CBFS.
BRANCH=None
