Fix N^2 behavior in _bfd_dwarf2_find_symbol_bias
A customer reported a case where addr2line was very slow. We tracked this down to some N^2 behavior in _bfd_dwarf2_find_symbol_bias in the unusual case where no function can be found. This patch fixes the bug, and reduces the runtime for a particular request from 127 seconds to 1 second. bfd/ChangeLog 2019-08-19 Tom Tromey <tromey@adacore.com> * dwarf2.c (_bfd_dwarf2_find_symbol_bias): Create hash table holding symbols.
