Loop relaxation logic in xtensa gas may produce code in which LEND register doesn't match actual zero overhead loop end. Fix relaxation code so that it produces a literal or a pair of const16 instructions with associated relocation record that works correctly in the presence of other relaxations. This fixes crash in X11 server caused by window movement. Loop relaxation has limited of 32K range, this fix removes this limitation.
