Linux DWARF reader: Follow DW_AT_abstract_origin links to find function names.

Browse source 
Without this patch, debugging information like the following will produce
FUNC records with no names, because the dumper (correctly) ignores the
DW_TAG_subprogram DIEs that lack DW_AT_low_pc/DW_AT_high_pc attributes, but
won't follow the DW_AT_abstract_origin link from the DIE that does have
code addresses to find its name.

 <1><168>: Abbrev Number: 5 (DW_TAG_class_type)
    <169>   DW_AT_name        : Foo	
 <2><183>: Abbrev Number: 7 (DW_TAG_subprogram)
    <185>   DW_AT_name        : Foo	
    <18b>   DW_AT_declaration : 1	
 <1><1b7>: Abbrev Number: 12 (DW_TAG_subprogram)
    <1b8>   DW_AT_specification: <0x183>	
    <1bc>   DW_AT_inline      : 2	(declared as inline but ignored)
