that breaks on big-endian machines.

I have to clean up the 32/64 bit confusion in libDebugInfo some day.

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.

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

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.

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.

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.
