In gccgo, we insert the write barriers in the frontend, and so we
cannot completely prevent write barriers on stack writes. So it
is possible for a bad pointer appearing in the write barrier
buffer. When flushing the write barrier, treat it the same as
sacnning the stack. In particular, don't mark a pointer if it
does not point to an allocated object. We already have similar
logic in greyobject. With this, hopefully, we can prevent an
unallocated object from being marked completely.

I'm trying to add a define_subst use in the arm backend but am getting many build errors complaining about:
`set_attr_alternative' is unsupported by `define_subst'
Looking at the gensupport.c code it iterates over all define_insns and errors if any of them have set_attr_alternative.
The usecase I'm targetting doesn't involve patterns with set_attr_alternative, so I would like to make the define_subst handling
more robust to only error out if the define_subst is actually attempted on a set_attr_alternative.
This patch produces the error only if the set_attr_alternative attr matches the subst name.
This allows a build of the arm backend with a define_subst usage to succeed.

gcc.target/i386/asm-4.c uses amd64's natural PC-relative addressing
mode on a single platform, using the 32-bit absolute addressing mode
elsewhere. There's no point in giving up amd64's natural addressing
mode and insisting on the 32-bit one when we're targeting amd64, and
having to make explicit exceptions for systems where that's found not
to work for whatever reason. If we just use the best-suited way to
take the address of a function behind the compiler's back on each
target variant, we're less likely to hit unexpected failures.

Honestly, I haven't really had much involvement with the frv, mn10300

processor_costs has costs of RTL expressions with pseudo registers and
and costs of hard register moves:
1. Costs of RTL expressions are used to generate the most efficient RTL
operations with pseudo registers.
2. Costs of hard register moves are used by register allocator to
decide how to allocate and move hard registers.
Since relative costs of pseudo register load and store versus pseudo
register moves in RTL expressions can be different from relative costs
of hard registers, we should separate costs of RTL expressions with
pseudo registers from costs of hard registers so that register allocator
and RTL expressions can be improved independently.
This patch moves costs of hard register moves to the new hard_register
field and duplicates costs of moves which are also used for costs of RTL
expressions.

In C++17 a function can return a prvalue of a type that cannot be moved
or copied. The current implementation of std::is_invocable_r uses
std::is_convertible to test the conversion to R required by INVOKE<R>.
That fails for non-copyable prvalues, because std::is_convertible is
defined in terms of std::declval which uses std::add_rvalue_reference.
In C++17 conversion from R to R involves no copies and so is not the
same as conversion from R&& to R.
This commit changes std::is_invocable_r to check the conversion without
using std::is_convertible.
std::function also contains a similar check using std::is_convertible,
which can be fixed by simply reusing std::is_invocable_r (but because
std::is_invocable_r is not defined for C++11 it uses the underlying
std::__is_invocable_impl trait directly).
