    25  * This is a simple test that checks that access specialization in FinalizeTypes is consistent.

    26  * Here, a2 = 0 will be turned int {I}a2 = 0, and all would be fine and well, only we can't change

    27  * the symbol type for a2 from double, and we can't as it's not a temporary. Either we have to put

    28  * a temporary in at the late finalize stage and add another assignment, or we genericize the check

    29  * in CodeGenerator#Store so we detect whether a target is of the wrong type before storing. It

    30  * is hopefully very rare, and will only be a problem when assignment results that have been

    31  * specialized live on the stack
