  [IR] fix spelling/formatting; NFC

Even within this file, the usual spelling is 'Opcode',
so make it consistent.

  Changed paths:
    M llvm/lib/Transforms/InstCombine/InstCombineAddSub.cpp
    M llvm/test/Transforms/InstCombine/addsub-constant-folding.ll

  Log Message:
  -----------
  [InstCombine] reassociate subtract-from-constant to add-constant

(C - X) + Y --> (Y - X) + C

Moving the constant operand to an 'add' gives more
flexibility to subsequent reassociation patterns,
and it may be better for codegen on targets that
don't have subtract-from-immediate instructions.
