These are really useful hints to the compiler in the absence of link-time

I've made the const attribute be ATTRIBUTE_CONST unlike other function
attributes, because we have other things in the tree #defining CONST for
their own unrelated purposes.
Mindly related: how people feel about making these macros less screamy,
by following the approach used in the kernel: PURE -> __pure and so on ?
I'd love it.
Less screamy is fine, but beware prefixing double underscore: the C
standard stipulates that its use is reserved for for C/C++ runtime. [1]
Look at stdlibc++ implementation: every internal variable has a double
underscore prefix.
Maybe kernel gets away on GLIBC (and because it doesn't use C++), but
there's no guarantee it will work on other C runtimes, and even if it
does, it could start failing anytime.
