* dwarf2read.c (dwarf2_linkage_name): New function to get

the linkage name of a die from DW_AT_MIPS_linkage_name or
	DW_AT_name.
	(read_func_scope, dwarf2_add_field, dwarf2_add_member_fn,
	new_symbol):  Use it instead of accessing DW_AT_name.
	(read_partial_die):  Use DW_AT_MIPS_linkage name as name of the
	partial die if present.
	(dwarf2_add_member_fn):  Make a copy of physname on the type obstack.
