ICE using new attributes(..) section of #[proc_macro_derive]

[sfackler]

I'm seeing an ICE at this commit: sfackler/rust-postgres-derive@50d93bd

Not sure if it's a derive issue or an issue with that lint - cc @keeperofdakeys

error: internal compiler error: ../src/librustc_metadata/decoder.rs:490: entry: id not found: DefIndex(1) in crate "postgres_derive" with number 12

note: the compiler unexpectedly panicked. this is a bug.

note: we would appreciate a bug report: https://github.com/rust-lang/rust/blob/master/CONTRIBUTING.md#bug-reports

note: run with `RUST_BACKTRACE=1` for a backtrace

I can confirm that this ICE also happens with my own derive crate, which worked on the original PR that I submitted. So I suspect that another PR may have changed something. However, there are rpass-fulldeps tests, so I'm not sure how this snuck through. Note that the derive crate itself compiles fine, the ICE only happens when compiling a crate which uses a derive crate.

When I get some time, I'll start investigating this. I'm unfamiliar with the code where the panic is happening, but it must be related to my PR somehow.

Happened upon this bug on a project using Serde:

error: internal compiler error: ../src/librustc_metadata/decoder.rs:490: entry: id not found: DefIndex(1) in crate "serde_derive" with number 41

note: the compiler unexpectedly panicked. this is a bug.

This was caused by #37542 -- I'll fix today.
