This patch addresses the bogus "Invocation mismatch" messages seen in parallel
profiledbootstrap builds of gcc. See PR bootstrap/55051 for a discussion of
why this is occurring and why this checking is inaccurate. Leave it in when
!GCOV_LOCKED, to warn about concurrent update issues requiring locking.
