[C++ PATCH] Don't redefine __* builtins (PR c++/84724)

Hi! The C FE just warns and doesn't override builtins, but C++ FE on say int __builtin_trap (); will override the builtin, so later builtin_decl_explicit will return the bogus user function which e.g. doesn't have any merged attributes, can have different arguments or return type etc. This patch
