IP_MULTICAST_TTL Time to live for multicast datagrams. This option
takes an unsigned character as an argument. Its
value is the TTL that IP uses on outgoing multi-
cast datagrams. The default is 1.
IP_MULTICAST_LOOP Loopback for multicast datagrams. Normally multi-
cast datagrams are delivered to members on the
sending host (or sending zone). Setting the
unsigned character argument to 0 causes the oppo-
site behavior, meaning that when multiple zones
are present, the datagrams are delivered to all
zones except the sending zone.

This reverts commit fd4a6a1.
A single framework for gen-kill and generic dataflow problems This is the prototype implementation discussed in rust-lang/compiler-team#202. You can read a high-level description of it in [the proposal](https://hackmd.io/@39Qr_z9cQhasi25sGjmFnA/Skvd9rztS) for that design meeting. This would eventually supersede the existing `BitDenotation` interface. r? @ghost cc @rust-lang/compiler (esp. @eddyb and @pnkfelix)
Simplify NodeHeader by avoiding slices in BTreeMaps with shared roots Simplify a complicated piece of code that creates slices of keys in node leaves.
…oli-obk Implement `?const` opt-out for trait bounds For now, such bounds are treated exactly the same as unprefixed ones in all contexts. [RFC 2632](rust-lang/rfcs#2632) does not specify whether such bounds are forbidden outside of `const` contexts, so they are allowed at the moment. Prior to this PR, the constness of a trait bound/impl was stored in `TraitRef`. Now, the constness of an `impl` is stored in `ast::ItemKind::Impl` and the constness of a bound in `ast::TraitBoundModifer`. Additionally, constness of trait bounds is now stored in an additional field of `ty::Predicate::Trait`, and the combination of the constness of the item along with any `TraitBoundModifier` determines the constness of the bound in accordance with the RFC. Encoding the constness of impls at the `ty` level is left for a later PR. After a discussion in \#wg-grammar on Discord, it was decided that the grammar should not encode the mutual exclusivity of trait bound modifiers. The grammar for trait bound modifiers remains `[?const] [?]`. To encode this, I add a dummy variant to `ast::TraitBoundModifier` that is used when the syntax `?const ?` appears. This variant causes an error in AST validation and disappears during HIR lowering. cc #67794 r? @oli-obk
