Optimize get_tuple_element instructions that target Y registers
Several improvements in the compiler (e.g. c288ab87fd6) has
lead to an Y register being the target for get_tuple_element
instructions. Therefore, introduce i_get_tuple_element2y
that combines two consecutive get_tuple_element instructions
that target Y registers.
