Andres Freund 1145acc70d Add a barrier primitive for synchronizing backends. 
Provide support for dynamic or static parties of processes to wait for
all processes to reach point in the code before continuing.

This is similar to the mechanism of the same name in POSIX threads and
MPI, though has explicit phasing and dynamic party support like the
Java core library's Phaser.

This will be used by an upcoming patch adding support for parallel
hash joins.
