Various improvements to DWARF handling to cope with changes in recent
versions of gcc as shipped with Fedora 12. Specific changes include:

  - Vastly increase the number of opcodes we understand how to
    evaluate when processing a location expression.

  - Process frame unwind data from the debug_frame ELF section as
    well as the eh_frame section.

  - Handle version 3 CIEs in frame unwind data.

  - Handle the compact form of DW_AT_data_member_location which just
    gives a constant offset from the start of it's base type instead
    of a full location expression.

Based on patches from Jakub Jelinek on bugs #210479 and #210566.
