(hard-reg-set.h): Included to get decl of `reg_names'.

Browse Source 
(PRINT_REG):  Default definition added.
(dwarf_last_decl):  Variable declaration added.
(output_reg_number):  New function; handle -fverbose-asm reg printing.
(output_mem_loc_descriptor, output_loc_descriptor):  Call it.
(output_decl):  Set `dwarf_last_decl' each time this fn is called.
