Documenting GCC 4.2 changes

[Martin Michlmayr <tbm at cyrius dot com>]

I went through the ChangeLog (2006 only so far) to identify command
line options that should be documented in the GCC 4.2 changes page at
http://gcc.gnu.org/gcc-4.2/changes.html

It would be nice if people listed below could submit patches for the
command line options they added/removed during the GCC 4.2 cycle.  I'm
not sure how important it is to document options mostly aimed at GCC
developers, but it would be great if at least changes to common user
options could be documented.
