Make clang compile the new i386 and x86_64 atomic code
The input type needs to match the output type, otherwise we get this
error:
src/corelib/arch/qatomic_x86_64.h:288:25: error: unsupported inline asm:
input with type '<dependent type>' matching output with type 'T':
"0" (valueToAdd * QAtomicAdditiveType<T>::AddScale)
