Yes.

Yes, and assemble_integer knows how to deal with
UNALIGNED_DOUBLE_INT_ASM_OP being null.

Would you please find out?

In general, it is not possible to replace dw2_asm_output_* with
assemble_integer, because we want to do things like emit

	.uaword	.L0 - .L1

which you cannot do in assemble_integer.  In fact, only one of the
N uses of unaligned_integer_asm_op in dwarf2asm.c is an integer
constant that could be broken down into pieces to emit.
