When we see the a '[' in a postfix expression in Objective-C, perform
a simple, quick check to determine whether the expression starting
with '[' can only be an Objective-C message send. If so, don't parse
it as an array subscript expression. This improves recovery for, e.g.,
[a method1]
[a method2]
so that we now produce
t.m:10:13: error: expected ';' after expression
[a method]
^
instead of some mess about expecting ']'.
