[PATCH] D135583: [LLVM] Use DWARFv4 bitfields when tuning for GDB

> What minimum compiler we require for building clang is a pretty different question than the one we're dealing with here.

Maybe I can clarify. I was thinking that if someone's `gcc` is 7.x then their `gdb` is likely 7.x as well. If they try to debug a binary produced with the clang they just built, they will likely reach for `gdb` not `lldb`. So that's why there's a link there.

But anyway you are correct it's not the main concern here. I will check the DWARF gcc produces across versions.
