6848dad894 Another performance tweak: Split the sqlite3BtreeCursorHasMoved() routine 
into two with the second routine named sqlite3BtreeCursorRestore().  The first
now only reports whether or not the cursor has moved and the second tries to
restore the cursor.  This allows the sqlite3VdbeCursorMoveto() routine to be
refactored to avoid stack pointer movements, for a noticable performance gain.

a1f7c0a21c Enhance the sqlite3VdbeRecordCompare() routines so that if they encounter 
database corruption, they will set the UnpackedRecord.isCorrupt field and
return 0.  The sqlite3BtreeMovetoUnpacked() routine detects this and returns
SQLITE_CORRUPT, causing the corruption to be reported back to the top-level.
