DO NOT MERGE: there are still issues around debuginfo and maybe even misoptimizations.
As suggested by @pcwalton, maybe it's time to test the overhead / wins from turning MIR inlining on.

thread 'rustc' panicked at 'missing specialization: `<decoder::DecodeContext as SpecializedDecoder<rustc::ich::Fingerprint>>::specialized_decode` not overridden', libserialize/serialize.rs:788:9

Maybe the specialization bugs weren't fixed, huh.
