PR preprocessor/53229 - Fix diagnostics location when pasting tokens

As stated in the audit trail of this problem report, consider this
test case:

    $ cat test.c
 1 struct x {
 2   int i;
 3 };
 4 struct x x;
 5
 6 #define TEST(X) x.##X
 7
 8 void foo (void)
 9 {
10   TEST(i) = 0;
11 }
    $

    $ cc1 -quiet test.c
    test.c: In function 'foo':
    test.c:10:1: error: pasting "." and "i" does not give a valid preprocessing token
       TEST(i) = 0;
     ^
    $

So, when pasting tokens, the error diagnostic uses the global and
imprecise input_location variable, leading to an imprecise output.

To properly fix this, I think libcpp should keep the token of the
pasting operator '##', instead of representing it with flag on the LHS
operand's token.  That way, it could use its location.  Doing that
would be quite intrusive though.  So this patch just uses the location
of the LHS of the pasting operator, for now.  It's IMHO better than
the current situation.

The patch makes paste_tokens take a location parameter that is used in
the diagnostics.  This change can still be useful later when we can
use the location of the pasting operator, because paste_tokens will
just be passed the new, more precise location.

Incidentally, it appeared that when getting tokens from within
preprocessor directives (like what is done in gcc.dg/cpp/paste12.c),
with -ftrack-macro-expansion disabled, the location of the expansion
point of macros was being lost because
cpp_reader::set_invocation_location wasn't being properly set.  It's
because when cpp_get_token_1 calls enter_macro_context, there is a
little period of time between the beginning of that later function and
when the macro is really pushed (and thus when the macro is really
expanded) where we wrongly consider that we are not expanding the
macro because macro_of_context is still NULL.  In that period of time,
in the occurrences of indirect recursive calls to cpp_get_token_1,
this later function wrongly sets cpp_reader::invocation_location
because cpp_reader::set_invocation_location is not being properly set.

To avoid that confusion the patch does away with
cpp_reader::set_invocation_location and introduces a new flag
cpp_reader::about_to_expand_macro_p that is set in the small time
interval exposed earlier.  A new in_macro_expansion_p is introduced as
well, so that cpp_get_token_1 can now accurately detect when we are in
the process of expanding a macro, and thus correctly collect the
location of the expansion point.

People seem to like screenshots.

Thus, after the patch, we now have:

    $ cc1 -quiet test.c
    test.c: In function 'foo':
    test.c:6:18: error: pasting "." and "i" does not give a valid preprocessing token
     #define TEST(X) x.##X
      ^
    test.c:10:3: note: in expansion of macro 'TEST'
       TEST(i) = 0;
       ^
    $

Bootstrapped and tested on x86_64-unknown-linux-gnu against trunk.

Make unwound macro expansion trace less redundant

As discussed previously, the unwinder for macro expansion is quite
verbose [1].  This patch proposes to address that shortcoming.

Consider this test case:

    $ cat -n test.c
 1 #define MYMAX(A,B) __extension__ ({ __typeof__(A) __a = (A); \
 2  __typeof__(B) __b = (B); __a < __b ? __b : __a; })
 3
 4 struct mystruct {};
 5 void
 6 foo()
 7 {
 8   struct mystruct p;
 9   float f = 0.0;
10   MYMAX (p, f);
11 }
    $

The output of the compiler from trunk yields:

    $ cc1 -quiet ./test.c
    ./test.c: In function ‘foo’:
    ./test.c:2:31: error: invalid operands to binary < (have ‘struct mystruct’ and ‘float’)
      __typeof__(B) __b = (B); __a < __b ? __b : __a; })
   ^
    ./test.c:2:31: note: in expansion of macro 'MYMAX'
      __typeof__(B) __b = (B); __a < __b ? __b : __a; })
   ^
    ./test.c:10:3: note: expanded from here
       MYMAX (p, f);
       ^
    $

After this patch, the compiler yields:

    $ ./cc1 -quiet ./test.c
    ./test.c: In function ‘foo’:
    ./test.c:2:31: error: invalid operands to binary < (have ‘struct mystruct’ and ‘float’)
      __typeof__(B) __b = (B); __a < __b ? __b : __a; })
   ^
    ./test.c:10:3: note: in expansion of macro 'MYMAX'
       MYMAX (p, f);
       ^
    $

The gotcha is, in the general case, we cannot simply eliminate the
context of the macro definition.  That is, the line from the first
output that is redundant with the first diagnostic line that has
line/column number:

    ./test.c:2:31: note: in expansion of macro 'MYMAX'
      __typeof__(B) __b = (B); __a < __b ? __b : __a; })
                                   ^

We cannot simply eliminate that context of macro definition because
there are cases where the first diagnostic that has a line/column
number doesn't point to a location inside the definition of the macro
where the relevant token is used.  For instance:

    $ cat -n test2.c
 1 #define OPERATE(OPRD1, OPRT, OPRD2) \
 2   OPRD1 OPRT OPRD2;
 3
 4 #define SHIFTL(A,B) \
 5   OPERATE (A,<<,B)
 6
 7 #define MULT(A) \
 8   SHIFTL (A,1)
 9
10 void
11 g ()
12 {
13   MULT (1.0);// 1.0 << 1; <-- so this is an error.
14 }
    $

Which yields without the patch:

    $ cc1 -quiet ./test2.c
    ./test2.c: In function ‘g’:
    ./test2.c:5:14: error: invalid operands to binary << (have ‘double’ and ‘int’)
       OPERATE (A,<<,B)
  ^
    ./test2.c:2:9: note: in expansion of macro 'OPERATE'
       OPRD1 OPRT OPRD2;
     ^
    ./test2.c:5:3: note: expanded from here
       OPERATE (A,<<,B)
       ^
    ./test2.c:5:14: note: in expansion of macro 'SHIFTL'
       OPERATE (A,<<,B)
  ^
    ./test2.c:8:3: note: expanded from here
       SHIFTL (A,1)
       ^
    ./test2.c:8:3: note: in expansion of macro 'MULT'
       SHIFTL (A,1)
       ^
    ./test2.c:13:3: note: expanded from here
       MULT (1.0);// 1.0 << 1; <-- so this is an error.
       ^
    $

Here, the line that has the context of macro definition:

    ./test2.c:2:9: note: in expansion of macro 'OPERATE'
       OPRD1 OPRT OPRD2;
     ^
is useful, because the first diagnostic that has line/column number
wasn't pointing into the definition of the macro OPERATE, where the
token '<<' is used.

    ./test2.c:5:14: error: invalid operands to binary << (have ‘double’ and ‘int’)
       OPERATE (A,<<,B)
  ^
So in this this case, displaying the macro definition context is not
redundant.  I think it is even desirable.

The patch changes the output in that case to be:

    ./test2.c: In function ‘g’:
    ./test2.c:5:14: erreur: invalid operands to binary << (have ‘double’ and ‘int’)
       OPERATE (A,<<,B)
  ^
    ./test2.c:2:9: note: in definition of macro 'OPERATE'
       OPRD1 OPRT OPRD2;
     ^
    ./test2.c:8:3: note: in expansion of macro 'SHIFTL'
       SHIFTL (A,1)
       ^
    ./test2.c:13:3: note: in expansion of macro 'MULT'
       MULT (1.0);// 1.0 << 1; <-- so this is an error.
       ^
    $

It's shorter, but I believe it has all the information that was
present before the patch.
