The thunk generation is needlessly complex, given that it attempts to deal with variable length instructions, which don't exist on AArch64. So replace it with a simple template coded in assembler, with a matching struct definition in C. That way, we can create and manipulate the thunks easily without looping over the instructions looking for 'magic' numbers. Also, use x16 rather than x9, since it is the architectural register to use for thunks/veneers.
