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.
