This ensures the instructions are marked as code instead of data, which is important when using tools like llvm-bolt.

i'm no longer working at Google. @talumbau ?

Note, the usage of .word directives to encode ARM dot-product instructions is for historical purposes: back in 2018 this was bleeding-edge and not supported on the then-current Android NDK toolchain. This could all be dropped now. The normal asm instruction to replace the .word directive should always be in the comment on the same line.
