C++ 20 modules

[Nathan Sidwell]

Several issues have been fixed today:
* Solaris headers 98315 (hopefully finally)
* install-strip  98328
* clang offsetof 98323 (I typoed the PR in the commit)
* libcody enable-checking 98311 (thanks Jakub for the followup)
* source_location etc fix from Jonathan
* More dashisms
* detailed-mem-stat init issue

I'm aware of the following:
* 98324  bootstrap with lto/PIE.  I can reproduce this, investigating
* 98300  windows build, reporter has indicated patch gets further
* 98316  solaris socket lib, Rainer is developing a patch
