sim: moxie: replace custom "word" type with int32_t

This is a 32-bit architecture with 32-bit registers, so replace the
custom "word" int typedef with an explicit int32_t.  Practically
speaking, this produces the same code, but it should hopefully make
it easier to merge common code in the future.
