Benjamin Kramer 112ec17e1b DWARF: Reset the state after parsing a line table prologue and remove an unnecessary lookup.

Benjamin Kramer 901339d070 DWARF: Don't crash when looking up an invalid address.

Benjamin Kramer 2602ca67e8 DWARF: Put all the pieces we have together and provide a single accessor to DIContext that provides line information when given an address.

Benjamin Kramer 679e1752f8 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.

Benjamin Kramer 6dda032003 DWARF: Print line tables per compile unit, so they get the right address size.

Benjamin Kramer 07d4b1c455 DWARF: wire up .debug_str dumping.

Benjamin Kramer 5acab501de DWARF: Add basic support for line tables.
The llvm-dwarfdump output isn't very verbose yet.

Benjamin Kramer 3266493603 DWARF: Generate the address lookup table from the DIE tree if .debug_aranges is not available.
Ported from LLDB.

Benjamin Kramer a6002fd920 DWARF: Port support for parsing .debug_aranges section from LLDB and wire it up to llvm-dwarfdump.
This is only one half of it, the part that caches address ranges from the DIEs when .debug_aranges is
not available will be ported soon.

Benjamin Kramer aa2f78f5e6 Sketch out a DWARF parser.
This introduces a new library to LLVM: libDebugInfo. It will provide debug information
parsing to LLVM. Much of the design and some of the code is taken from the LLDB project.

It also contains an llvm-dwarfdump tool that can dump the abbrevs and DIEs from an
object file. It can be used to write tests for DWARF input and output easily.
