When converting value blocks from HIR to ReactiveFunction, we have to drop StoreLocal assignments that represent the assignment of the phi, since ReactiveFunction supports compound expressions. These StoreLocals are only present to represent the conditional assignment of the value itself - but it's also possible for the expression to have contained an assignment expression. Before, in trying to strip the first category of StoreLocal we also accidentally stripped the second category. Now we check that the assignment is for a temporary, and don't strip otherwise.
