Eric Christopher 7370b55262 Rewrite DIContext interface to take an object. Update all callers.

Alexey Samsonov 9cb13d59b7 Fixup for r167558: Store raw pointer (instead of reference) to RelocMap in DIContext. This is needed to prevent crashes because of dangling reference if the clients don't provide RelocMap to DIContext constructor.

Eric Christopher 7c678de861 Add a relocation visitor to lib object. This works via caching relocated 
values in a map that can be passed to consumers. Add a testcase that
ensures this works for llvm-dwarfdump.

Alexey Samsonov 034e57a297 Add basic support for .debug_ranges section to LLVM's DebugInfo library. 
This section (introduced in DWARF-3) is used to define instruction address
ranges for functions that are not contiguous and can't be described
by low_pc/high_pc attributes (this is the usual case for inlined subroutines).
The patch is the first step to support fetching complete inlining info from DWARF.

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.
