This matches ld64, and makes dsymutil work better with lld's output.
Fixes PR54783, see there for details.

Reduces time needed to run dsymutil on Chromium Framework from 8m30s
to 6m30s and removes many lines of "could not find object file symbol for
symbol" from dsymutil output (previously: several MB of those messages, now
dsymutil is completely silent).
