add missing cc clobbers to intel atomic inlines
On x86, the inc/dec/add/or/and instructions set [er]flags according to the result of the calculation. This means that the atomic_* static inlines need to specify the "cc" clobber register otherwise we risk the compiler not realizing that the flags have changed and suble bugs appearing.
