Re-install temporary reverted patch:
* toplev.c (rest_of_compilation): Call split_all_insns
before reg-stack and shorten-branches. Do shorten-branches
after reg-stack.
* final.c (shorten_branches): Remove insn splitting code.

* doc/gcc.texi, doc/invoke.texi: Add index of command line
options. Use @opindex to index them rather than other indexing
commands. Use @var{...} instead of <...>. Avoid spaces in names
inside @var. Don't use @kindex to index escape sequences in
source code.

Don't set BINFO_VTABLE for a primary virtual base.

* libsupc++/eh_alloc.cc: Ensure that required macros are
defined before including gthr.h. Ensure that we get the
version of gthr.h for which we know how to provide a
configuration.
* libsupc++/eh_globals.cc: Likewise. And, bring the threading
code path into line with the current EH model. Use std, where
appropriate.
