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.

(instead of basenames) from DWARF. Use this behavior in llvm-dwarfdump tool.

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.

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

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

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.

llvm-dwarfdump: Make the "is debug info section" heuristic stricter so it doesn't accidentaly picks up the wrong section.

Also add some validation code to the aranges section parser.

Fixes PR10926.
