RFR: 8356328: Some C2 IR nodes miss size_of() function

I wrote a test to check if every C2 IR node has correct size_of() function. And I found some of them are missed. They added new fields and not add size_of() to reflect new size. In linux, it does not cause issue so far, because gcc allocate more space for alignment and can keep these additional `bool` flags. But it will report failure on windows. And if anyone modified base class, it will cause problem.

PS, My test is in https://github.com/openjdk/jdk/compare/master...kuaiwei:jdk:test/check_node_size , but it has many hack on IR nodes to make test to run.
