The RTTI generation is in ncgrtti.pas. It makes use of the typed const
builder, which is one of the few parts of the compiler that's
documented: https://wiki.freepascal.org/Generating_initialised_data
(although that documentation hasn't been updated in quite a while, so it
may be a bit out of date).
