Options

Add -mgnu-asm; change -mdec-asm to generate DEC assembler 

        compatible output.

	(pdp11_output_labelref): New.
	(pdp11_output_def): New.
	(pdp11_output_addr_vec_elt): New.
	* config/pdp11/pdp11.c: Use tab between opcode and operands.  Use
	%# and %@ format codes.

	(output_ascii): Use .ascii/.asciz for -mdec-asm.
	(pdp11_asm_print_operand): Update %# and %$ for -mdec-asm.  Add
	%o, like %c but octal.

	* config/pdp11/pdp11.h (TEXT_SECTION_ASM_OP): Update for
	-mdec-asm.
	(DATA_SECTION_ASM_OP): Ditto.
