Bytecode function.
Contains links to the bytecode of the function, as well as metadata describing all arguments and stack-local variables.
When calling a function, all argument values must be on the stack.
If the function has a This pointer (i.e. hasThisPointer() returns true, the argument values need to be preceeded by a Pointer for the This object.
If the function uses Return Value Optimization, the arguments (and potentially the This pointer) need to be proceeded by a Pointer pointing to the location to construct the returned value.
After the function has been called, it will remove all arguments, including RVO and This pointer, from the stack.
