builtin-types.def (BT_FN_STRING_CONST_STRING): New builtin type.
* builtin-types.def (BT_FN_STRING_CONST_STRING): New builtin type.
(BT_FN_PTR_SIZE_SIZE): Likewise.
* builtins.def (BUILT_IN_MALLOC, BUILT_IN_CALLOC, BUILT_IN_STRDUP):
New built-in functions for malloc, calloc and strdup respectively.
* calls.c (special_function_p): No need to handle malloc-like
functions any longer. ECF_MALLOC is set via built-in attributes.
* c-decl.c (duplicate_decls): Preserve pure and malloc attributes.
* cp/decl.c (duplicate_decls): Preserve pure and malloc attributes.
* f/com.c (duplicate_decls): Preserve pure and malloc attributes.
* doc/extend.texi: Document these new built-in functions.
* gcc.dg/builtins-13.c: New test case.
