This commit fixes two bugs in the C++ reflection implementation related to comparing reflections. The first bug was a crash in cp_tree_equal when comparing reflections with binfos. The second bug was in compare_reflections when comparing two aliases, where it incorrectly fell back to same_type_p. The fix ensures that comparing aliases correctly distinguishes between them.
