ranges more similar to the console output.  Consider:

#define FOO(X, Y) X/ Y

void foo(int *P, int *Q) {
  FOO(P, Q);
}

Before we emitted:

t.c:4:3:{4:3-4:6}{4:3-4:6}: error: invalid operands to binary expression ('int *' and 'int *')
   FOO(P, Q);
   ^~~~~~~~~
...

Note that while we underline the macro args that the range info just includes FOO 
without its macros.  This change teaches the printed ranges to include macro args
also so that we get:

t.c:4:3:{4:3-4:12}{4:3-4:12}: error: invalid operands to binary expression ('int *' and 'int *')
   FOO(P, Q);
   ^~~~~~~~~
...

"GCC emits an __objc_class_name_{classname} symbol for every class, and a corresponding reference to this symbol for every compilation unit that references the class.  This causes linker errors when you try linking a program which references some classes but doesn't define them.  The attached patch implements this support in clang, so you can compile a class with clang, reference it in a file compiled with GCC, and have it all work correctly."

that were suppressed due to SFINAE. By checking whether any errors
occur at the end of template argument deduction, we avoid the
possibility of suppressing an error (due to SFINAE) and then
recovering so well that template argument deduction never detects that
there was a problem. Thanks to Eli for the push in this direction.

llvm-svn: 73336

Implement support for C++ Substitution Failure Is Not An Error
(SFINAE), which says that errors that occur during template argument
deduction do *not* produce diagnostics and do not necessarily make a
program ill-formed. Instead, template argument deduction silently
fails. This is currently implemented for template argument deduction
during matching of class template partial specializations, although
the mechanism will also apply to template argument deduction for
function templates. The scheme is simple:

  - If we are in a template argument deduction context, any diagnostic
    that is considered a SFINAE error (or warning) will be
    suppressed. The error will be propagated up the call stack via the
    normal means.
  - By default, all warnings and errors are SFINAE errors. Add the
    NoSFINAE class to a diagnostic in the .td file to make it a hard
    error (e.g., for access-control violations).

Note that, to make this fully work, every place in Sema that emits an
error *and then immediately recovers* will need to check
Sema::isSFINAEContext() to determine whether it must immediately
return an error rather than recovering.
