[S390] use inline assembly contraints available with gcc 3.3.3
Drop support to compile the kernel with gcc versions older than 3.3.3. This allows us to use the "Q" inline assembly contraint on some more inline assemblies without duplicating a lot of complex code (e.g. __xchg and __cmpxchg). The distinction for older gcc versions can be removed which saves a few lines and simplifies the code.
