Ilya Leoshkevich df103c09bc target/s390x: Fix cc_calc_sla_64() missing overflows 
An overflow occurs for SLAG when at least one shifted bit is not equal
to sign bit. Therefore, we need to check that `shift + 1` bits are
neither all 0s nor all 1s. The current code checks only `shift` bits,
missing some overflows.

Fixes: cbe24bfa91 ("target-s390: Convert SHIFT, ROTATE SINGLE")
