eliminate PL_regdummy

This global (per-interpreter) var is just used during regex compilation as
a placeholder to point RExC_emit at during the first (non-emitting) pass,
to indicate to not to emit anything. There's no need for it to be a global
var: just add it as an extra field in the RExC_state_t struct instead.
