Currently, single-stepping is tied to GDB debugging. This means that when
EXCP_DEBUG is returned, a debug exception is triggered in many cases. We
define a new EXCP_SINGLESTEP to differentiate the case where we want a
single step to not be tied to a debug exception. We also define a new flag
for cpu->singlestep_enabled called SSTEP_NODEBUG which is set when we want
to use single-step for purposes other than debugging.
