re PR middle-end/44671 (Partial inlining breaks C++)
PR middle-end/44671
PR middle-end/44686
* tree.c (build_function_decl_skip_args): Clear DECL_BUILT_IN on signature
change.
* ipa-split.c (split_function): Always clear DECL_BUILT_IN.
* ipa-prop.c (ipa_modify_formal_parameters): Likewise.
* gcc.c-torture/pr44686.c: New file.
