 Log Message:
 gcc: lib*san: Enable built-in 64-bit atomic ops for !__HAVE_ATOMIC64_OPS
 
 as already done for some mips platforms by upstream.
 
 Now, libubsan (as well as libasan if platform itself is supported)
 work on some ILP32 platforms.
 
 Fix PR port-sparc/58352.
 
 This may be slower than another possible fix where all 64-bit atomic
 variables are replaced by 32-bit ones. But, it should still be better
 than having relatively large diffs to upstream; sanitizers are not
 enabled for normal use, anyway.
 
 XXX
 Note that filename confusion in upstream codes:
 - "sanitizer_atomic_clang.h" is used also for GCC.
 - "sanitizer_atomic_clang_mips.h" has no mips specific codes.
