Up to now, SerializableSnapshot and QuerySnapshot are malloc'ed and
free'd for every transaction or statement, respectively.  This patch
puts these data structures into static memory, thus saving a few CPU
cycles and two malloc calls per transaction or (in isolation level
READ COMMITTED) per query.
