Andrew Kaylor 9a8ff813f3 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.

Andrew Kaylor d55d7019fc 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.

Alexey Samsonov 45be793e3a 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.

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.

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.

The llvm-dwarfdump output isn't very verbose yet.
