Thanks!
The patch needed bit of updating for new command line parsing code. I
am attaching what I am going to commit now (once testing finishes)
* Makefile.in (web.o): New.
* web.c: New file.
* rtl.h (web_main): Declare.
* timervar.def (TV_WEB): New.
* toplev.c (dump_file_index, dump_file_info): Add DFI_web.
(rest_of_hanle_web): New.
(flag_web): New static variable.
(lang_independent_options): Add "web".
(rest_of_compilation): Call rest_of_handle_web.
* invoke.texi (-fweb): Document.
* common.opt (fweb): New.
* flags.h (flag_web): New.
* opts.c (decode_options): Set flag_web at -O3.
* passes.texi (web construction): Document.
* invoke.texi (-O3): Document that -fweb is enabled.
