Add basic support for .debug_ranges section to LLVM's DebugInfo library.
This section (introduced in DWARF-3) is used to define instruction address ranges for functions that are not contiguous and can't be described by low_pc/high_pc attributes (this is the usual case for inlined subroutines). The patch is the first step to support fetching complete inlining info from DWARF. Reviewed by Benjamin Kramer. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@162657 91177308-0d34-0410-b5e6-96231b3b80d8
