Merge #1444
1444: Handle `rustc_const_{un}stable` properly for intrinsics r=CohenArthur a=CohenArthur
Since extern functions cannot be marked as const (they take no
qualifiers) but some intrinsics are const, while still being `extern
"rust-intrinsic", we need to be able to handle the
`#[rustc_const_stable]` and `#[rustc_const_unstable]` attribute.
Technically, this simply indicates that a certain intrinsic is constant
and can be used in const contexts, such as `size_of` or `offset`.
We also need to mark all const intrinsics with `rustc_const_stable` in
the testsuite.
Closes #1440
