This patch to the website moves the section about the selftest suite to
the bottom of "Other significant improvements" section, and rewrites it
to also cover the GIMPLE and RTL "frontends", and tries to couch these
changes in terms of the benefit to the end-user (i.e. a more reliable
compiler).
Validates.
