* Try to avoid spilling of an imm register if it contains a value loaded from an already spilled imm register. It likely leads to an endless loop and the register allocation fails.

make rgobj.uses_registers also return true, when the rg never allocated an imreg, but there were direct cpu register allocations. this at least fixes some address regvar trashing on 68k in relation to syscalls' explicit paralocs

* Make trgobj.uses_registers method return True when registers of appropriate type are specified in list of used registers (after assembler blocks), but not used otherwise. This is a missing piece of r30011, enabling code generator to actually save/restore such registers. Resolves #28421.
