change the block and stmt position after a function call returns 
previously we moved to the target block *before* calling a function, so when inspecting
the stack, it appeared as if we were in the first statement of the next block.

don't execute the first statement of a constant/static/promoted right away 
This might create confusion, because attempting to execute a statement can cause
arbitrary stackframes to be added for the constants/statics/promoteds required by that
statement. Before this commit, the first statement of the last added stackframe was
executed immediately. Thus there was no way to inspect the state before that first
statement.
