Yeah, HImode sounds right in this case.

For a 16-bit target, word_mode should be HImode rather than SImode.
The way the modes are defined is that QImode is always one "unit"
(byte), HImode is always twice the size of QImode, SImode is always
twice the size of HImode, and so on. Other modes like word_mode,
Pmode and ptr_mode are defined relative to that.
