Adding a fix-it hint currently involves changing e.g.:

  error_at (token->location,
            "unknown type name %qE; did you mean %qs?",
            token->value, hint);
to:

  gcc_rich_location richloc (token->location);
  richloc.add_fixit_replace (hint);
  error_at_rich_loc (&richloc,
                     "unknown type name %qE; did you mean %qs?",
                     token->value, hint);

to make the change from taking a location_t to a rich_location *.

This patch renames the "*_at_rich_loc" diagnostic entrypoints to use
the same function names for rich_location * as for location_t,
via overloading, to simplify the above change to just changing from:

  error_at (token->location,
            "unknown type name %qE; did you mean %qs?",
            token->value, hint);
to:

  gcc_rich_location richloc (token->location);
  richloc.add_fixit_replace (hint);
  error_at (&richloc,
            "unknown type name %qE; did you mean %qs?",
            token->value, hint);

thus saving space (and typing) and usually avoiding the need to reindent
the "error_at" invocation.

With this change, 0 is no longer acceptable as a location_t to these
entrypoints, as e.g.:

../../src/gcc/auto-profile.c:855:37: error: call of overloaded
'inform(int, const char [18])' is ambiguous
       inform (0, "Not expected TAG.");
                                     ^
In file included from ../../src/gcc/auto-profile.c:35:0:
../../src/gcc/diagnostic-core.h:88:13: note: candidate:
'void inform(location_t, const char*, ...)'
 extern void inform (location_t, const char *, ...) ATTRIBUTE_GCC_DIAG(2,3);
             ^~~~~~
../../src/gcc/diagnostic-core.h:89:13: note: candidate:
'void inform(rich_location*, const char*, ...)'
 extern void inform (rich_location *, const char *, ...) ATTRIBUTE_GCC_DIAG(2,3);
             ^~~~~~

Such locations now need to be spelled out as UNKNOWN_LOCATION,
rather than 0.

I considered making the API take a rich_location & rather than a
rich_location *, but doing so would mean replacing
  diagnostic_set_info
and
  diagnostic_set_info_translated
with a constructor for diagnostic_info, which was a more invasive
change.  Maybe in the future.

If the user asks for a stack clash probe interval of 64kB, we currently
generate a "stdu rX,-65536(r1)" instruction.  That instruction does not
exist (the offset is a 16-bit signed number).  If the offset is too big

A left shift of 1 can always be done using an add, so slightly adjust rtx
cost for DImode left shift by 1 so that adddi3 is preferred in all cases,
and the arm_ashldi3_1bit is redundant.

DImode right shifts of 1 are rarely used (6 in total in the GCC binary),
so there is little benefit of the arm_ashrdi3_1bit and arm_lshrdi3_1bit
patterns.  The generated code is better and faster without these shifts
as it allows early expansion, optimization and better register allocation.

    gcc/
	* config/arm/arm.md (ashldi3): Remove shift by 1 expansion.
	(arm_ashldi3_1bit): Remove pattern.
	(ashrdi3): Remove shift by 1 expansion.
	(arm_ashrdi3_1bit): Remove pattern.
