Benjamin Kramer 2602ca67e8 DWARF: Put all the pieces we have together and provide a single accessor to DIContext that provides line information when given an address.

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.

Benjamin Kramer 973b5cde7e 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.

Benjamin Kramer a6002fd920 DWARF: Port support for parsing .debug_aranges section from LLDB and wire it up to llvm-dwarfdump.
This is only one half of it, the part that caches address ranges from the DIEs when .debug_aranges is
not available will be ported soon.

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.
