First step, handle diagnostics in StringLiteral's that are due to token pasting.
For example, we now handle:
id str2 = @"foo"
"bar"
@"baz"
" b\0larg"; // expected-warning {{literal contains NUL character}}
Correctly:
test/SemaObjC/exprs.m:17:15: warning: CFString literal contains NUL character
" b\0larg"; // expected-warning {{literal contains NUL character}}
~~~^~~~~~~
There are several other related issues still to be done.
