[PATCH] Fix PR c++/13560 wrong file reported for file

[Andrew Pinski]

We were printing out the wrong file name for a function because
the location which we change the diagnostic to.  The way to fix
this is to have cp_error_at print out the starter before having
to report diagnostic.  This what this patch do.

OK? Bootstrapped and tested on powerpc-apple-darwin.

Thanks,
Andrew Pinski

Testcase (which I don't know how to get into the testsuite):
# 1 "<built-in>"
# 1 "<command line>"
# 1 "test.cc"
# 1 "test.h" 1
class t
{
  int g;
};
void h(t&);
# 2 "test.cc" 2

int main()
{
   t y;
   h(y);
   return y.g;
}

ChangeLog:
	* error.c (cp_error_at): Output the context as it might be
	different file as the other location.
