This makes the implementation of the detection and propagation of the suspendable property simpler and easier to read. More importantly, there are no more jumps around the AST with the `visit` functions, which in some cases could result in incorrect visitor context while in the `visit` function. See the added test, which would cause Verilator to segfault before this patch. In testing, verilation performance was not shown to be affected by this change. Though there is a slight performance improvement from this patch, due to adding one more check before refreshing class member cache. Signed-off-by: Krzysztof Bieganski <kbieganski@antmicro.com>
