[PATCH] D92844: [gn build] Link with -Wl,--gdb-index

[Arthur Eubanks via Phabricator via llvm-commits]

>> 15% slower links seems noticeable. I'd prefer putting this behind a flag (can default to `is_debug` if you really want). I think putting all optional compiler/linker command line flags behind gn args makes sense.

Yup
