Internally we noticed that some tests would fail like so on Windows: warning: Section .debug_aranges in [...] has duplicate debug_info_offset 0x0, ignoring .debug_aranges. Debugging showed that, in fact, a second CU was being created at this offset. We tracked this down to the fact that, while the ELF reader is careful to re-use the per-BFD data, other readers are not, and could re-read the DWARF data multiple times. However, since the change to allow an objfile to have multiple "quick symbol" implementations, there's no reason for this approach -- it's safe and easy for all symbol readers to reuse the per-BFD data when reading DWARF. This patch implements this idea, simplifying dwarf2_build_psymtabs and making it private, and then switching to dwarf2_initialize_objfile as the sole way to start the DWARF reader. Note that, while I think the call to dwarf2_build_frame_info in machoread.c is also obsolete, I haven't attempted to remove it here.
