GlobalISel: Fix matchEqualDefs for instructions with multiple defs

Instructions that produceSameValue produce same values for operands with
same index. matchEqualDefs used to return true for any two values from
different instructions that produce same values. Fix this by checking if
values are defined by operands with the same index.
