tst_QFlags: make constExpr() check compile on clang trunk
The problem is the verifyConstExpr<>() line involving the ~ operator.
The result as an integer is a value that can no longer be represented
in an int. This is known at compile time and thus template deduction,
which only has an int to match against, fails.
To fix, use an unsigned int as the first template argument of
verifyConstExpr<>().
Clang's error message for this is really sub-optimal, cf.
