Make a nicer output when QBasicAtomicInteger is used with a wrong T

Browse Source 
Before, we'd get just an error message that the size of the array was
negative. Now, for C++11 compilers, we get a better error message:

qbasicatomic.h:117:5: error: static assertion failed: Template parameter is not a supported integer on this platform
qbasicatomic.h:119:24: error: invalid use of incomplete type ‘struct QAtomicOps<long long unsigned int>’
