This makes llvm-dwarfdump and llvm-symbolizer understand
debug info sections compressed by ld.gold linker.

This allows llvm-dwarfdump to handle the relocations needed, at least
for LLVM-produced code.

The test is a binary placed in test/DebugInfo/Inputs, with a source C
file used for reference/reproducing. The source's first line is a clang
build command for reproducing the binary.

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.

by instruction address from DWARF.
Add --inlining flag to llvm-dwarfdump to demonstrate and test this functionality,
so that "llvm-dwarfdump --inlining --address=0x..." now works much like
"addr2line -i 0x...", provided that the binary has debug info
(Clang's -gline-tables-only *is* enough).

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.

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.

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
