libstdc++: Fix simd test compilation with Clang
Signed-off-by: Matthias Kretz <m.kretz@gsi.de>
libstdc++-v3/ChangeLog:
* testsuite/experimental/simd/tests/operators.cc: Clang doesn't
define __GCC_IEC_559. Use __STDC_IEC_559__ instead.
(cherry picked from commit 25db59017f2e216a76c8a0fe4814568135f19f9a)
