Currently we don't insert an intermediate `SyntacticElement` locator element for the `if` statement in a SingleValueStmtExpr, which leads to an assertion failure when attempting to simplify a following `TernaryBranch` element. Move the insertion of the `SyntacticElement` locator element for the statement into the SingleValueStmtExpr constraint generation function, and remove it from the statement visitors themselves. For the other cases, the `SyntacticElement` was already being inserted for children of a BraceStmt, so we were actually previously ending up with duplicated elements in a couple of places.
