libstdc++: Add missing clear_padding in __atomic_float constructor
For 80-bit long double we need to clear the padding bits on
construction.
libstdc++-v3/ChangeLog:
* include/bits/atomic_base.h (__atomic_float::__atomic_float(Fp)):
Clear padding.
* testsuite/29_atomics/atomic_float/compare_exchange_padding.cc:
New test.
