Node::InputCount() and ::InputAt() have to check for inline/out-of-line inputs every time they are called. The compiler doesn't seem to be very good at caching the result of this check, meaning that it (and all its jumps) would happen for every node access. Previously we would get around this sometimes, by using Node::inputs(), which returned a Node::Inputs iterable over node inputs. However, sometimes node access is more convenient using an index, or we also want to access the count. This patch adds an index accessor and 'count' method to Node::Inputs, and replaces several uses of InputCount and InputAt with this accessor.
