Added more diff context.
With Hexagon there can be a penalty when jumping to an instruction that crosses an alignment boundary so especially for things like the top of a loop we don't want that instruction to cross that boundary.
I'm hoping to use instruction bundling to do this since it's the semantics we want but it also means we want bundling to be off usually and only on for specific instructions.
