Use ThrowHelper instead of inline exception throwing

The idea of the proposed change is to:

1. Make code generated methods smaller because the JIT emits jump to throw methods and doesn't inline them. The description of the trick can be found [here](https://github.com/dotnet/corefx/blob/56dfb8834fa50f3bc61ea9b4bfdc9dcc759b6ec9/src/System.Memory/src/System/ThrowHelper.cs#L11-L22).
2. ~Prevent duplication of exception messages.~
