Bug #21173: RUBY_FREE_AT_EXIT does not work when error in -r
https://bugs.ruby-lang.org/issues/21173

When loading a file using the command line -r, it is processed before RUBY_FREE_AT_EXIT is checked. So if the loaded file raises an error, it will cause memory to not be freed with RUBY_FREE_AT_EXIT.

For example `ruby -rtest.rb -e ""` will report a large amount of memory leaks if `test.rb` raises.
