For a function that takes a closure as default value, the array of
parameter reported by sourcekit also includes the parameters of that
closure.
In other words, a function like
func foo(param1: Int,
param2: Bool,
param3: (Int) -> Void = { (x: Int) in }) { }
reports 4 parameters (param 1, param2, param3, and x).
This commit uses the bounds of the method/function parameters to filter
out parameters within parameters. Below, a 1, a 2, and a 3 would be
filtered out since they're inside parameter 3.
