Doug Evans c52ab08aee target-i386: Fix eflags.TF/#DB handling of syscall/sysret insns
The syscall and sysret instructions behave a bit differently:
TF is checked after the instruction completes.
This allows the o/s to disable #DB at a syscall by adding TF to FMASK.
And then when the sysret is executed the #DB is taken "as if" the
syscall insn just completed.
