This is a dedicated instruction for incrementing a profiler counter, which lowers to the `llvm.instrprof.increment` intrinsic. This replaces the builtin instruction that was previously used, and ensures that its arguments are statically known. This ensures that SIL optimization passes do not invalidate the instruction, fixing some code coverage cases in `-O`. rdar://39146527
