Title: Clarify match?/2 docs.

I think because the subject usually is the first argument in Elixir, I expected the expression to be the left side. After looking at the implementation and realizing that it's supposed to mirror matching with `=`, it makes sense that the pattern is on the left side. However, I think it's worth it to make this a bit clearer in the docs.
