Implement CALLMETHOD, SH_STRUCTREF and PUSHSTRUCTPAGE instructions. Constructors are a bit tricky since SH_LOCALCREATE has to implicitly call an arbitrary number of functions before it returns (just changing the instruction pointer only allows for calling a single function). To get around this, there is now a vm_call() function which is used to call a function synchronously, before returning from the current instruction. Methods are implemented as functions, except that they get a struct page as local variable -1. Destructors are still not implemented.
