Обсуждение: pgsql: Add EXPLAIN support for JIT.

Add EXPLAIN support for JIT.

This just shows a few details about JITing, e.g. how many functions
have been JITed, and how long that took.  To avoid noise in regression
tests with functions sometimes being JITed in --with-llvm builds,
disable display when COSTS OFF is specified.
