38a6381c0a Refactor fetching file/line info from DWARFContext to simplify the
code and allow better code reuse. Make the code a bit more conforming
to LLVM code style.
No functionality change.

351f83be64 Fix the representation of debug line table in DebugInfo LLVM library,
and "instruction address -> file/line" lookup.

Instead of plain collection of rows, debug line table for compilation unit is now
treated as the number of row ranges, describing sequences (series of contiguous machine
instructions). The sequences are not always listed in the order of increasing
address, so previously used std::lower_bound() sometimes produced wrong results.
Now the instruction address lookup consists of two stages: finding the correct
sequence, and searching for address in range of rows for this sequence.

71d94f8055 DebugInfo library: add support for fetching absolute paths to source files
(instead of basenames) from DWARF. Use this behavior in llvm-dwarfdump tool.

Reviewed by Benjamin Kramer.

c26ed9b47f DWARF: Remove accessors that parse the whole line table section in one go, this can't possibly work.
The address size is specified by the compile unit associated with a line table, there is no global address size.

b848e97611 DWARF: Add basic support for line tables.
The llvm-dwarfdump output isn't very verbose yet.
