fortify: Use __diagnose_as() for better diagnostic coverage
In preparation for using Clang's __pass_object_size, add __diagnose_as() attributes to mark the functions as being the same as the indicated builtins. When __daignose_as() is available, Clang will have a more complete ability to apply its own diagnostic analysis to callers of these functions, as if they were the builtins themselves. Without __diagnose_as, Clang's compile time diagnostic messages won't be as precise as they could be, but at least users of older toolchains will still benefit from having fortified routines.
