In this case I think the mark_symbol_refs_as_used calls from
sh, s390 and arm backends can go away.
The calls are always next to an assemble_integer call, and while
s390 and arm provide their own ASM_INTEGER hook, they either call
output_addr_const directly, or for non-CONST_{INT,VECTOR} they
call default_assemble_integer which calls output_addr_const as well.
Perhaps it isn't needed in output_operand either.

At least until PR38237 is fixed, calling assemble_external multiple
times is very much visible in the generated assembly.
