[PATCH] D52261: [Sema] Generate completion fix-its for C code as well

It's the responsibility of the caller to provide a corrected expression, this keeps the completion function simpler. I suggest we stick to this contract.
We do something in `getLangOpts().CPlusPlus` case to create a corrected expression, let's just implement a similar fallback for C at the single callsite that we have (`ParsePostfixExpressionSuffix`).
