  [IRSim] Letting gep instructions be legal for similarity identification.

GetElementPtr instructions require the extra check that all operands
after the first must only be constants and be exactly the same to be
considered similar.

Tests are found in unittests/Analysis/IRSimilarityIdentifierTest.cpp.
