Ilya Leoshkevich 6da170beda target/s390x: Fix shifting 32-bit values for more than 31 bits
According to PoP, both 32- and 64-bit shifts use lowest 6 address
bits. The current code special-cases 32-bit shifts to use only 5 bits,
which is not correct. For example, shifting by 32 bits currently
preserves the initial value, however, it's supposed zero it out
instead.

Fix by merging sh32 and sh64 and adapting CC calculation to shift
values greater than 31.

Cho, Yu-Chen 98be64d2f4 target/s390x: split cpu-dump from helper.c
Splitting this functionality also allows us to make helper.c sysemu-only.
