jit: gcc diagnostics are jit errors

libgccjit performs numerous checks at the API boundary, but
if these succeed, it ignores errors and other diagnostics emitted
within the core of gcc, and treats the compile of a gcc_jit_context
as having succeeded.

This patch ensures that if any diagnostics are emitted, they
are visible from the libgccjit API, and that the the context is
flagged as having failed.

For now any kind of diagnostic is treated as a jit error,
so warnings and notes also count as errors.

* dummy-frontend.c: Include diagnostic.h.

Implement C11 DR#423 resolution (ignore function return type qualifiers).

The resolution of C11 DR#423, apart from doing things with the types
of expressions cast to qualified types which are only in standard
terms observable with _Generic and which agree with how GCC has
implemented _Generic all along, also specifies that qualifiers are
discarded from function return types: "derived-declarator-type-list
function returning T" becomes "derived-declarator-type-list function
returning the unqualified version of T" in the rules giving types for
function declarators.  This means that declarations of a function with
both qualified and unqualified return types are now compatible,
similar to how different declarations can vary in whether a function
argument is declared with a qualifier or unqualified type.

This patch implements this resolution.  Since the motivation for the
change was _Generic, the resolution is restricted to C11 mode; there's
no reason to consider there to be a defect in this regard in older
standard versions.  Some less-obvious issues are handled as follows:

* As usual, and as with function arguments, _Atomic is not considered
  a qualifier for this purpose; that is, function declarations must
  agree regarding whether the return type is atomic.

* By 6.9.1#2, a function definition cannot return qualified void.  But
  with this change, specifying "const void" in the declaration
  produces the type "function returning void", which is perfectly
  valid, so "const void f (void) {}" is no longer an error.

* The application to restrict is less clear.  The way I am
  interpreting it in this patch is that "unqualified version of T" is
  not valid if T is not valid, as in the case where T is a
  restrict-qualified version of a type that cannot be restrict
  qualified (non-pointer, or pointer-to-function).  But it's possible
  to argue the other way from the wording.

Bootstrapped with no regressions on x86_64-pc-linux-gnu.

Fix PR target/53440 - handle generic thunks better for TARGET_32BIT.

This partially fixes PR target/53440 atleast in ARM and
Thumb2 state. I haven't yet managed to get my head around
rewriting the Thumb1 support yet.

Tested on armhf with a bootstrap and regression test
with no regressions.

Queued for stage1 now as it isn't technically a regression.

regards
