ecb6bc5106 Tiny speed improvement to 6809 LZSA depackers 
Same space used but improved match length code by 1 cycle for M6809. On H6309 the clock cycles are the same.

214e03555f Slight speed improvement in 6809 LZSA depackers 
Switch instruction "tfr x,u" to "leau ,x" which is 2 clock cycles faster on M6809. On H6309 both instruction have same clock cycles.
