Include a pointer to the query's source text in QueryDesc structs. This is

practically free given prior 8.4 changes in plancache and portal management,
and it makes it a lot easier for ExecutorStart/Run/End hooks to get at the
query text.  Extracted from Itagaki Takahiro's pg_stat_statements patch,
with minor editorialization.
