Give Instruction::isSameOperationAs a corresponding comment to note

the relationship with MergeFunctions.cpp's isEquivalentOperation,
and make a trivial code reordering so that the two functions are
easier to compare.

Fix the name of Instruction::isSameOperationAs in MergeFunction.cpp's
isEquivalentOperation's comment, and fix a nearby 80-column violation.
