C: underline parameters in mismatching function calls

In r253096
  ("C++: underline parameters in mismatching function calls"
  aka 5d78d423a5f7a1d135c7bb678e82007678d1313c
    https://gcc.gnu.org/ml/gcc-patches/2017-09/msg01546.html )
I updated the C++ FE's handling of mismatched types in function calls
so that it underlines the pertinent param of the callee, rather than
just the function name.

The following patch does the same for the C frontend.

Given e.g. this type mismatch:

  extern int callee (int one, const char *two, float three);

  int caller (int first, int second, float third)
  {
    return callee (first, second, third);
  }

the C FE currently emits (trunk):

  test.c: In function 'caller':
  test.c:5:25: warning: passing argument 2 of 'callee' makes pointer from
  integer without a cast [-Wint-conversion]
     return callee (first, second, third);
                           ^~~~~~
  test.c:1:12: note: expected 'const char *' but argument is of type 'int'
   extern int callee (int one, const char *two, float three);
              ^~~~~~

whereas with this patch the note underlines the pertinent param of
the callee:

  test.c: In function 'caller':
  test.c:5:25: warning: passing argument 2 of 'callee' makes pointer from
  integer without a cast [-Wint-conversion]
     return callee (first, second, third);
                           ^~~~~~
  test.c:1:41: note: expected 'const char *' but argument is of type 'int'
   extern int callee (int one, const char *two, float three);
                               ~~~~~~~~~~~~^~~

making the problem more obvious to the user.

As with the C++ patch, the patch:

(a) updates the locations of the params to cover the range of all
of their tokens, putting the caret on the first character of the
param name (if present), otherwise at the start of the first token
(doing so requires adding a last_token_location to the c_parser, so
we can determine the location of the last consumed token).

(b) updates the "note" to use the param location, rather than the
fndecl location

gcc/c/ChangeLog:
* c-decl.c (push_parm_decl): Store c_parm's location into the
PARAM_DECL.

parameter, and pass it to the call to build_c_parm.
* c-tree.h (struct c_parm): Add field "loc".

Fix PR82396: qsort comparator non-negative on sorted output

r253236 broke AArch64 bootstrap. Earlier revision r253071 changed scheduling
behaviour on AArch64 as autopref scheduling no longer checks the base.

This patch fixes the bootstrap failure and cleans up autopref scheduling.
The code is greatly simplified.  Sort accesses on the offset first, and
only if the offsets are the same fall back to other comparisons in
rank_for_schedule.  This doesn't at all restore the original behaviour
since we no longer compare the base address, but it now defines a total
sorting order.  More work will be required to improve the sorting so
that only loads/stores with the same base are affected.
