AFAIU, top_level_run executes the top level code of a file.  I.e. it
usually creates a lot of functions and puts them into the
symbol-function slots; for lambdas it puts the subr in d_reloc (see
comp--register-lambda).

In general, top_level_run can trigger GC flips because it calls
make_subr a lot.  It would be problematic if d_reloc where not traced
during those GC flips.  text_data_reloc_eph probably too, but I have no
clue what that is for.
