  Forward-port of commit 59184.

  - Backported a workaround for a bug in SQLite 3.2.x/3.3.x versions where a
    statement recompilation with no bound parameters lead to a segfault
  - Backported a fix necessary because of an SQLite API change in version
    3.5.
    This prevents segfaults when executing empty queries, like our test suite
    does
