Checks the bytecode of *frame* to find the name of the variable a result is
being assigned to and returns that name. Returns the full left operand of the
assignment. Raises a #ValueError if the variable name could not be retrieved
from the bytecode (eg. if an unpack sequence is on the left side of the
assignment).
