runtime: add edge lockRankSysmon -> lockRankRwmutexR Sysmon can actually get the RW lock execLock while holding the sysmon lock (if no M is available), so there is an edge from lockRankSysmon to lockRankRwmutexR. The stack trace is sysmon() [gets sched.sysmonlock] -> startm() -> newm() -> newm1() -> execLock.runlock() [gets execLock.rLock] Change-Id: I9658659ba3899afb5219114d66b989abd50540db Reviewed-on: https://go-review.googlesource.com/c/go/+/265721 Trust: Dan Scales <danscales@google.com> Reviewed-by: Michael Knyszek <mknyszek@google.com>
