Update gcc6809 patch to fix an ICE. Add new gcc6809 patch with a fix to an internal compiler error reported by Tormod Volden. It seems whoever created the offending instruction patterns didn't fully understand the instruction contraints system and likely got away with it due to characteristics of the instruction generator in previous versions of gcc. Alas, it causes problems now so unless someone has a brilliant idea how to make it work, addhi_mem_1 and addhi_mem_minus1 have to go. Fortunately, the compiler is smart enough to use an alternate strategy all on its own.
