b3ad4e6118 Defer deletion of expressions that are optimized out by the AND optimizer
in the sqlite3ExprAnd() routine until the corresponding Parse object is
deleted.  This avoids a dangling pointer in AggInfo if sqlite3ExprAnd()
is invoked by the push-down optimization.  The dangling pointer appears
to be harmless in release builds, only showing up in debug builds.
Problem found by dbsqlfuzz.

opcodes, allowing them to run faster.  This required refactoring the
vector comparison logic, which in turn required changing OP_ElseNotEq into
