Add 'warning density' computation to the warnhist script (#3910)
* Add 'warning density' computation to the warnhist script, along with several
cleanups to it. Add "--enable-show-all-warnings" configure (and CMake)
option to disable compiler diagnostic suppression (and therefore show all the
otherwise suppressed compiler diagnostics), disabled by default. Clean up
a buncn of misc. warnings.
