Avoid calling sqlite3VdbeCursorMoveto() from more than one point in vdbe.c. Doing so prevents it from being inlined as part of OP_Column.

The sqlite3ExprCodeGetColumn() is not guaranteed to put the result in the
...
register requested. Fix the skip-scan code generator for WITHOUT ROWID
tables so that it always checks the register and copies the result if it
lands in the wrong register. Fix for ticket [8fd39115d8f46ece70e7d4b3].
