Unwrap symbols for debug information

Browse source 
Fixes issues with dwz multi-file (-m) and ld's -wrap option.
Symbols referenced from DWARF debug info in a separate file, eg. to
specify low and high pc, must use the real symbol.  The DWARF info
is specifying attributes of the real function, not one interposed
with --wrap.
