Under specific circumstances for Ada programs, such as in the testcase
this change adds, the DWARF back-end currently crashes because of
inconsistent internal state. This is due to a typo: a local variable is
called frame_offset_ but resolve_args_picking_1 wrongly modifies
emit-rtl.h's frame_offset instead.
This change fixes this typo.

PR 70687 reports a case where combine.c mishandles integer modes
wider than unsigned HOST_WIDE_INT. I don't have a testcase since
the PR is just pointing out the hole.
Also, I think a ZERO_EXTEND of a vector mode could in principle satisfy
the subreg condition but wouldn't be equivalent to an AND. E.g.:
(zero_extend:V4DI (subreg:V4SI (reg:V4DI R) 0))
Tested on x86_64-linux-gnu.

When we emit a hint about a misspelled member name, it will slightly
aid readability if we use a fixit-hint to show the proposed
name in context within the source code (and in the future this
might support some kind of auto-apply in an IDE).
This patch adds such a hint to the C++ frontend, taking us from:
test.cc:10:15: error: 'struct foo' has no member named 'colour'; did you mean 'color'?
return ptr->colour;
^~~~~~
to:
test.cc:10:15: error: 'struct foo' has no member named 'colour'; did you mean 'color'?
