8090a24bd6 DWARFDebugLine.cpp: Fix true path. Did you forget "return true" here?

e27a787760 Add DIContext::getLineInfoForAddressRange() function and test. This function allows a caller to obtain a table of line information for a function using the function's address and size.

ee7c0d2f93 Add support for applying in-memory relocations to the .debug_line section and, in the case of ELF files, using symbol addresses when available for relocations to the .debug_info section. Also extending the llvm-rtdyld tool to add the ability to dump line number information for testing purposes.

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.

101b1c5ff1 DWARF: Put all the pieces we have together and provide a single accessor to DIContext that provides line information when given an address.

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.
