* 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.

Also check for the type of the register when replacing it. In certain circumstances this can still lead to access to invalid memory resulting either in an access violation or invalid registers.
