Comment (by nickm):

 This is a really good idea!  It might be biting off more than I can chew
 this week, however: when I did a quick-and-dirty test here, I found that
 only 57% of our headers currently build on their own, even after the fixes
 in #32764.  That leaves 177 headers to fix, which is a lot to tackle.

 I think that maybe we could do this without special handling for
 HAVE_MODULE_*; since our CI runs with the full matrix of disable-module-
 foo, then we should learn about any headers where we've broken with a
 module turned off.

 I'm going to hack on my quick-and-dirty test script a bit more, then
 upload it so we can iterate and improve it.
