Something I neglected to mention. The ARM-ARM suggests that MOVT and
MOVW should be synthesized by the assembler for MOV immediates that
can't be expressed by a <shifter_operand>. I did not implement this.
Also, it's possible to intuit from the existence of relocations for
these instructions in the Mar 8 revision of ARMELF, that they should
allow most link-time expressions as well as bare immediates. I did
not implement that, either. (Both are in the pipeline.)
