Hi Richard,

Don't invalidate TB with the end of zero overhead loop when LBEG or LEND
change. Instead encode the distance from the TB start to the LEND in the
TB flags and generate loopback code when offset of the next PC from the
TB start equals that distance. Distance not greater than the maximal
instruction
