Optimize `Trace`.
`Trace::FromOutlivesConstraint` contains an `OutlivesConstraint`, which is 72 bytes. Lots of these are created but never used. This commit splits `Trace::FromOutlivesConstraint` into three new variants: `FromVanilla`, `FromStatic`, `FromMember`. Each of these contains just enough data to construct an `OutlivesConstraint`, if necessary. This reduces the size of `Trace` from 72 bytes to 16 bytes. All this avoids some memory traffic.
