[Bug c/13804] New: Error message enhancement Request

[don_sfw at dlaster dot com]

When developing developing software I will get this error once in a while
         structure has no member named '<member-name>'

due to typos and other typical development gotchas.  It would be useful if the
error message included the structure name if known or associated pointer or
variable if the compiler has the information available for the error message.

 I often use the same structure member names in mulitple structures since I use
names that convey the use of member.  If the message was something like this

          structure '<structure-name>' has no member named '<member-name>'

or this

          '<variable>' structure '<structure-name>' has no member named
'<member-name>'

it would make it easier to locate the proper reference in more complicated
statements.

Confirmed on the mainline here is a small testcase to go with this report:
struct t
{
 int k;
};
void j()
{
  struct t p;
  p.d = 1;
}

We should say that d is not a member of the struct t.

As a side note, the C++ frontend emits this diagnostic for the same testcase:

diag.cc: In function `void j()':
diag.cc:8: error: 'struct t' has no member named 'd'

Yes, this is because the C front-end uses a different diagnostic (more
primitive) infrastructure than C++.  I have been unifying them, but
did not have time to finish.
