    When a defer is executed at most once in a function body,
    we can allocate the defer record for it on the stack instead
    of on the heap.
    
    This should make defers like this (which are very common) faster.
    
    This is a port of CL 171758 from the gc repo.

    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

stepped up and took over, but until someone does, I don't mind
