auto merge of #18592 : alexcrichton/rust/dylib-harder, r=pcwalton
eca8f11 
If a dylib is being produced, the compiler will now first check to see if it can
be created entirely statically before falling back to dynamic dependencies. This
behavior can be overridden with `-C prefer-dynamic`.

Due to the alteration in behavior, this is a breaking change. Any previous users
relying on dylibs implicitly maximizing dynamic dependencies should start
passing `-C prefer-dynamic` to compilations.

Closes #18499

Since the `ManuallyDrop` it returns can be safely used to consume the `Arc`, which is can cause UB if done incorrectly. See rust-lang#18499.
