The A32/T32 gen_intermediate_code_internal() is complicated because it
has to deal with:
* conditionally executed instructions
* Thumb IT blocks
* kernel helper page
* M profile exception-exit special casing
None of these apply to A64, so putting the "this is A64 so
call the A64 decoder" check in the middle of the A32/T32
loop is confusing and means the A64 decoder's handling of
things like conditional jump and singlestepping has to take
account of the conditional-execution jumps the main loop
might emit.
Refactor the code to give A64 its own gen_intermediate_code_internal
function instead.
