Split use of SerialSLRULock, creating SerialControlLock
predicate.c has been using SerialSLRULock (the control lock for its SLRU
structure) to coordinate access to SerialControlData, another of its
numerous shared memory structures; this is unnecessary and confuses
further SLRU scalability work. Create a separate LWLock to cover
SerialControlData.
Extracted from a larger patch from the same author, and some additional
changes by Álvaro.
