The new -fgo-c-header=FILE option will write a C header file defining
all the struct types and numeric const values in package scope. This
will be used when building the Go runtime package (libgo/go/runtime) to
generate a C header file that may be included by the C code in the C
runtime package (libgo/runtime).
This will ensure that the Go code and C code are working with the same
data structures as we convert the runtime from C to Go to upgrade to the
current GC runtime, notably the concurrent garbage collector.

The first aspect of this patch is to add some checking of fix-it hints.
The idea is to put this checking within the rich_location machinery,
rather than requiring every diagnostic to implement it for itself.
The fixits within a rich_location are "atomic": all must be valid for
any to be applicable.
We reject any fixits involving locations above
LINE_MAP_MAX_LOCATION_WITH_COLS.
There's no guarantee that it's sane to modify a macro, so we reject
any fix-its that touch them.
For example, note the attempt to provide a fix-it for the definition
of the macro FIELD:
spellcheck-fields-2.c: In function ‘test_macro’:
spellcheck-fields-2.c:26:15: error: ‘union u’ has no member named ‘colour’; did you mean ‘color’?
#define FIELD colour
^
color
spellcheck-fields-2.c:27:15: note: in expansion of macro ‘FIELD’
return ptr->FIELD;
^~~~~
After this patch, the fixit is not displayed:
spellcheck-fields-2.c: In function ‘test_macro’:
spellcheck-fields-2.c:26:15: error: ‘union u’ has no member named ‘colour’; did you mean ‘color’?
#define FIELD colour
^
spellcheck-fields-2.c:27:15: note: in expansion of macro ‘FIELD’
return ptr->FIELD;
^~~~~
We might want some way for a diagnostic to opt-in to fix-its that
affect macros, but for now it's simplest to reject them.
The other aspect of this patch is fix-it consolidation: in some cases
neighboring fix-its can be merged. For example, in a diagnostic to
modernize old-style struct initializers from:
struct s example = {
- foo: 1,
+ .foo = 1,
};
one approach would be to replace the "foo" with ".foo" and the ":"
with " =". This would give two "replace" fix-its:
foo: 1,
--- FIXIT 1
.foo
- FIXIT 2
=
This patch allows them to be consolidated into a single "replace" fix-it:
foo: 1,
----
.foo =

Previous, fix-it hints were printed using the color of the severity
of the diagnostic (magenta for warnings, red for errors, cyan for
notes).
This patch updates fix-it hints so that replacement text is printed in
green, to better distinguish the suggested improvement from
the current code. For example:
spellcheck-fields.cc:52:13: error: 'struct s' has no member named 'colour'; did you mean 'color'?
return ptr->colour; <<< RED
^~~~~~ <<< RED
color <<< GREEN
It makes sense for the underlinings that indicate deletions to
be printed in red, so the patch changes that also. For example:
diagnostic-test-show-locus-color.c:179:9: warning: example of a removal hint
int a;; <<< MAGENTA
^ <<< MAGENTA
- <<< RED
