m68k: support loading of refs to data registers, also when explicit paraloc is set and it's a register, use that directly, this fixes several syscall-related corner cases on Amiga

* m68k: do not emit moves between same register, they end up in wrong code in some cases when register needs to be spilled (and entirely useless otherwise).

m68k: do not generate CLR instructions to memory references on plain 68k. there this instruction also causes reads from the address, which is slow and can have side effects.

+ m68k, a_load_const_reg: use MOV3Q if applicable for data registers as well, since it allows spilling replacement of destination.

* m68k: fixed extension in a_load_ref_reg. Existing code cleans only bits 16-31 when loading a 8-bit register from 16-bit reference, and leaves garbage in bits 8-15.

* m68k: initial support for ROL/ROR operations, defining 'cpurox' for CPU target can actually enable them. However it cannot be done outright because these instructions do not exits on Coldfire, and internal processing of RoX,Sar,BsX, etc. can not yet be switched depending on CPU subtype.
