libc/atomic: Fix membars in __atomic_load/store_* stubs.

- membar_enter/exit ordering was backwards.
- membar_enter doesn't make any sense for load anyway.
- Switch to membar_release for store and membar_acquire for load.

The only sensible orderings for a simple load or store are acquire or
release, respectively, or sequential consistency. This never
provided correct sequential consistency before -- we should really
make it conditional on memmodel but I don't know offhand what the
values of memmodel might be and this is at least better than before.

make some prototypes match the builtin properly. GCC 9 complains
with the old version, GCC 8 is happy with this version.

tested on sparc.

branches: 1.2.2; 1.2.6; 1.2.28;
Add unused memory model argument to make GCC happy.


# 1.1 05-Jul-2014 joerg

Provide a basic implementation of __atomic_load_* and __atomic_store_*,
used by GCC and LLVM as backing for C11/C++11 atomics, if the hardware
is not known to have corresponding features. Include it on ARM as LLVM
and libc++ hit it when compiled for ARMv4.
