8.5.4 H8/300 Machine Directives

as has only one machine-dependent directive for the H8/300:

.h8300h

Recognize and emit additional instructions for the H8/300H variant, and also make .int emit 32-bit numbers rather than the usual (16-bit) for the H8/300 family.

On the H8/300 family (including the H8/300H) `.word' directives generate 16-bit numbers.
