    Improved algorithm. It's actually the same algorithm with second loop removed and simpler temporary data structures. The only difference may be in "re-defined" vatriable handling. Now live-range in that case started from the seconnd definition (this must be more safe).

8430ec1788 fix FCGI crash in TS mode 
If CGI TS build is used, and there are some hard errors (fe missing
dependency .dll or .so), the core will want to log it. The CGI
log function will want to check whether fcgi_logging is enabled. But,
if this kind of error happens in the extension register phase,
MINIT for the CGI module is most likely wasn't run yet (startup phase).
That will result in accessing uninitialized globals and a crash.
