allow UDA-like syntax for some keyword attributes

there is some inconsistency between UDA-like attributes like '@trusted',
'@nogc' and so on and non-UDA-like attributes like 'pure' or 'nothrow'. we
can't force using UDA-syntax for latter, but we can at least allow it, so user
shouldn't remember that 'nothrow' is a keyword and '@safe' is an attribute.

this patch allows using some keyword attributes as UDAs. i.e. user can write:

    void foo () @safe @nothrow @pure { … }

old syntax is supported too:

    void foo () @safe nothrow pure { … }

so no code will be broken.
