x86, traps: converge do_debug handlers
Make the x86_64-version and the i386-version of do_debug
more similar.
- introduce preempt_conditional_sti/cli to i386. The preempt-count
is now elevated during the trap handler, like on x86_64. It
does not run on a separate stack, however.
- replace an open-coded "send_sigtrap"
- copy some comments
