David Blaikie 1e47d1d24b DebugInfo: Add a CU metadata attribute for use of DWARF ranges base address specifiers ... Summary: Ranges base address specifiers can save a lot of object size in relocation records especially in optimized builds. For an optimized self-host build of Clang with split DWARF and debug info compression in object files, but uncompressed debug info in the executable, this change produces about 18% smaller object files and 6% larger executable. While it would've been nice to turn this on by default, gold's 32 bit gdb-index support crashes on this input & I don't think there's any perfect heuristic to implement solely in LLVM that would suffice - so we'll need a flag one way or another (also possible people might want to aggressively optimized for executable size that contains debug info (even with compression this would still come at some cost to executable size)) - so let's plumb it through.
