Some little fixes on QEMU
- some vectors can be declared as "const" - test on CONFIG_VNC_TLS is done for two times while just one is enough.

fix alpha cmovxx instruction
The CMOV instruction is defined by the alpha manual as:
CMOVxx Ra.rq,Rb.rq,Rc.wq !Operate formatCMOVxx Ra.rq,#b.ib,Rc.wq !Operate format
Operation:IF TEST THENRc ← Rbv
The current qemu behavior inverses Ra and Rb. This is fixed by this...
CRIS: Mask off the cache selection bit after MMU translations.
