366050e89a Add the "stmts" virtual table to the amalgamation, activated when compiled 
using -DSQLITE_ENABLE_STMTSVTAB.  Add the SQLITE_STMTSTATUS_REPREPARE and
SQLITE_STMTSTATUS_RUN statistics outputs from sqlite3_stmt_status() and add
corresponding columns to the stmts virtual table.  Change the numeric value
of SQLITE_STMTSTATUS_MEMUSED to get it out of the way of counter values.

3039e3698d The query planner examines the values of bound parameters to help determine 
if a partial index is usable.  Reprepares may happen if the bindings change.
This behavior is disabled by the QPSG setting.
