This macro was converted to the TARGET_STRUCT_VALUE_RTX hook many years
ago, however there are still some lingering definitions, and a use in
libobjc. All the remaining definitions define the macro to 0, which
libobjc treats the same as undefined, so it won't break anything else to
have libobjc stop checking the macro. However it may be that this part
of libobjc has been broken for a long time on targets that only define
the hook, but that is a separate issue.

movtf is unnecessary as a separate expander. Move this to be with
the standard scalar floating point expanders.
Achieved by adding a new iterator and then using the same.
Tested cross aarch64-none-elf and no regressions.

Solaris 12 changes the stat_[amc]tim members of struct stat from
timestruc_t to timespec_t for XPG7 compatiblity, thus breaking the libgo
build. The following patch checks for this change and uses the common
stat_atim.go if appropriate.

Some host-target combinations get bogus warnings about orig_dup
being used uninitialized. I tried to coerce the current uninit
pass to handle this case, but the patch I ended up with only worked
by accident because of the strange way in which the pass handles
limit cases. (If we have more than MAX_NUM_CHAINS chains, it silently
drops the excess chains and continues regardless, so it's quite easy
to come up with cases where the predicates for either the definition
or the use consider an arbitrary subset of the actual conditions.)
For now this patch turns -Wmaybe-uninitialized into a warning for
the affacted function. It will be a warning even if someone turns
off warnings on the command line, but I don't think that's important.
Bootstrapped and regression-tested on x86_64-linux-gnu. Also tested
with a cross-compiler to sparc-linux-gnu (which also triggered the
warning for me).

If an argument is marked as nonnull then passing in a NULL argument
will produce bad results even if the code checks against NULL. GCC
might optimize such checks away so warn the user when the function
contains such comparisons.
