-----------------------------------

Passing `--copt=-gpubnames` to the compiler greatly speeds up lldb (time to pause at the first breakpoint goes down from ~1min to ~1 second). Pass it by default in .bazelrc for the dbg config.

The downside is that the resulting binary is even larger (~2.1gb instead of 1.5)
