libstdc++: Change test to work without 64-bit atomics
This fixes a linker error for older ARM cores without 64-bit atomics.
I think the { dg-add-options libatomic } is no longer needed, but it's
harmless to keep it there.
libstdc++-v3/ChangeLog:
* testsuite/29_atomics/atomic_float/value_init.cc: Use float
instead of double so that __atomic_load_8 isn't needed.
