DWARF parser: Fix DWARF-2/3 incompatibility: size of DW_FORM_ref_addr is the same as DW_FORM_addr in DWARF2, and is 4/8 bytes on 32/64-bit DWARF starting from DWARF3. Adding a test for this is a huge pain - generating and uploading pre-built binary with DWARF3 debug info is way too ugly, and writing fine-grained unittests for DebugInfo is impossible, as it doesn't expose any headers in include/llvm. That said, I'm going to choose the second approach and submit the patch exposing DebugInfo headers for review soon enough.

Previously, parsing capability of the .debug_frame section was added

to lib/DebugInfo, with dumping in llvm-dwarfdump. This patch adds
initial ability to parse and dump CFA instructions contained in

To keep it manageable, the patch omits some more advanced capabilities
(accounted in TODOs):
* Parsing of instructions with BLOCK arguments (expression lists)
* Dumping of actual instruction arguments (currently only names are
dumped). This is quite tricky since the dumper has to effectively
"interpret" the instructions.

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.

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.
