In cleaning up C++'s handling of hidden decls, I renamed its DECL_BUILTIN_P, which checks for loc == BUILTINS_LOCATION to DECL_UNDECLARED_BUILTIN_P, because the location gets updated, if user source declares the builtin, and the predicate no longer holds. The original name was confusing me. (The builtin may still retain builtin properties in the redeclaration, and other predicates can still detect that.) I discovered that tree.h had its own variant 'DECL_IS_BUILTIN', which behaves in (almost) the same manner. And therefore has the same mutating behaviour. This patch deletes the C++ one, and renames tree.h's to DECL_IS_UNDECLARED_BUILTIN, to emphasize its non-constantness. I guess _IS_ wins over _P gcc/ * tree.h (DECL_IS_BUILTIN): Rename to ...
