This patch introduces support for specifing views in .loc directives, so that the compiler can use the assembler to generate line number information and have the assembler determine view numbers to multiple views at the same program counter.
binutils* dwarf.c (struct State_Machine_Registers): Add view field.
(reset_state_machine): Reset view.
(process_extended_line_op): Reset view when appropriate.
(display_debug_lines_raw): Increment or reset view when appropriate.
Print nonzero views. Support print view resets, disabled by default.
(display_debug_lines_decoded): Likewise. Disambiguate op_code tests,
enabling printing of end_sequence.

immediately when view option is given.
(process_entries): Avoid set_address to reset view when a known
address change already implies the view reset.
