Correct relative jumps range and adjust it for single core without delay-slot.
Setting bits 16 to 31 to 1 is incorrect, offset is shift
by two so bit 16 can be zero for jumps in range -64k to -128k.
Adjust relative offsets to compute target address same, as if there
is delay slot, for CPU variant without delay slot.
This allows to use same/standard MIPS assembler for mode
without delay slots.
