Add a testcase for rdar://21362748 [WWDC Lab] QoI: cannot subscript a value of type '[Int]?' with an index of type 'Int'

We used to produce:

test.swift:6:20: error: cannot subscript a value of type '[Int]?' with an index of type 'Int'
  return foo.array[0]
                   ^

with the recent subscript improvements we now produce:
error: result type 'Element' does not match expected type

which still isn't a great diagnosis, but at least is the correct problem.
