[vm/compiler] Do not use call->ArgumentAt(0) to access receiver.

If call can have type arguments we can't use call->ArgumentAt(0) to
access receiver, instead we need to use call->ArgumentAt(call->FirstArgIndex()).

This lead to a bug in polymorphic inlining of functions with type
arguments - instead of loading class id from the receiver we would be
loading it from the first argument which contains type arguments.

This CL also cleans up other parts of the compiler that used ArgumentAt(0)
when they needed receiver.
