For instance:
template <class T> void E() {};
class F {};
void test() {
::E<::F>();
E<::F>();
}
Gives the following error messages:
error: found '<::' after a template name which forms the
digraph '<:' (aka '[') and a ':', did you mean '< ::'?
::E<::F>();
^~~
< ::
error: expected expression
E<::F>();
^
error: expected ']'
note: to match this '['
E<::F>();
This patch adds the digraph fix-it check right before the name lookup,
moves the shared checking code to a new function, and adds new
tests to catch future regressions.

- This is designed to make it obvious that %clang_cc1 is a "test variable"
which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it
can be useful to redefine what gets run as 'clang -cc1' (for example, to set
a default target).
