When parsing a CREATE TABLE from the sqlite_master table, delete the CHECK
...
constraints if there are any errors, since there might otherwise be attempts
to use those CHECK constraints if PRAGMA writable_schema=ON is set.
This undoes the fix in check-in [ea721b34477ab8b4] for a more general
solution.

Work toward reducing the incremental size of an ExprList object to 24-byte
...
per entry, from 32-bytes (on a 64-bit machine). This helps the new
mini-lookaside allocator to run better by avoiding excessive reallocs.
The current change mostly works, but still has a few loose ends to tie up.
This check-in is merely a snapshot to save my work.

Omit the check for conflicting shared-cache locks in sqlite3Prepare() if the

database connection uses no shared cache. We might be able to go back and
remove this code completely, due to the newer Schema.iGeneration logic, but
that will take more analysis. This check-in gives the speed benefit but not
the reduction in code size.
