Improve the TB execution logging so that it is easier to identify
what is happening from trace logs:
  * move the "Trace" logging of executed TBs into cpu_tb_exec()
    so that it is emitted if and only if we actually execute a TB,
    and for consistency for the CPU state logging
  * log when we link two TBs together via tb_add_jump()
  * log when cpu_tb_exec() returns early from a chain of TBs

The new style logging looks like this:

Trace 0x7fb7cc822ca0 [ffffffc0000dce00]
Linking TBs 0x7fb7cc822ca0 [ffffffc0000dce00] index 0 -> 0x7fb7cc823110

Looks good, though I quibble over the term "Abandoned". To me that implies that nothing got executed, which isn't true. I'd prefer "Stopped" or "Exited".

Otherwise,
