Alexey Samsonov 947228c4f7 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.

Alexey Samsonov e16e16add6 DebugInfo library: add support for fetching absolute paths to source files 
(instead of basenames) from DWARF. Use this behavior in llvm-dwarfdump tool.

Alexey Samsonov b604ff2a07 Improve behavior of DebugInfoEntryMinimal::getSubprogramName() introduced in r159512. 
To fetch a subprogram name we should not only inspect the DIE for this subprogram, but optionally inspect
its specification, or its abstract origin (even if there is no inlining), or even specification of an abstract origin.

Alexey Samsonov f4462fa3ca This patch extends the libLLVMDebugInfo which contains a minimalistic DWARF parser: 
1) DIContext is now able to return function name for a given instruction address (besides file/line info).
2) llvm-dwarfdump accepts flag --functions that prints the function name (if address is specified by --address flag).
3) test case that checks the basic functionality of llvm-dwarfdump added

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.
