Subject: When trace_lwlocks is used, identify individual lwlocks by name.

Naming the individual lwlocks seems like something that may be useful
for other types of debugging, monitoring, or instrumentation output,
but this commit just implements it for the specific case of
trace_lwlocks.

Patch by me, reviewed by Amit Kapila and Kyotaro Horiguchi
