1. JitArm64: Never check downcount on block entry …

   Jumping between linked blocks currently works as follows: First, at the
   end of the first block, we check if the downcount is greater than zero.
   If it is, we jump to the `normalEntry` of the block. So far so good. But
   if the downcount wasn't greater than zero, we jump to the `checkedEntry`
   of the block, which checks the downcount *again* and then jumps to
   `do_timing` if it's less than zero (which seems like an off by one error
   - Jit64 doesn't do anything like this). This second check is rather
   redundant. Let's jump to `do_timing` where we previously jumped to
   `checkedEntry`.
   
   Jit64 doesn't check the downcount on block entry. See 5236dc3.

3. JitArm64: Use farcode in WriteLinkBlock …

   Now block link nearcode is back to a length of three instructions.
   
   Unfortunately, the code I'm adding to Jit.cpp ends up being a bit messy
   because we need to handle the case of already being in farcode...
