cmd/compile: fix incorrect shift count type with s390x rules
The type of the shift count must be an unsigned integer. Some s390x
rules for shift have their auxint type being int8. This results in a
compilation failure on s390x with an invalid operation when running
make.bash using older versions of go (e.g: go1.10.4).
This CL adds an auxint type of uint8 and changes the ops for shift and
rotate to use auxint with type uint8. The related rules are also
modified to address this change.
Fixes #43090
