-* A note on nomenclature of linking: "extern", "foreign", and "upcall".

-* An "extern" is an LLVM symbol we wind up emitting an undefined external
-* reference to. This means "we don't have the thing in this compilation unit,
-* please make sure you link it in at runtime". This could be a reference to
-* C code found in a C library, or rust code found in a rust crate.
-*
-* Most "externs" are implicitly declared (automatically) as a result of a
-* user declaring an extern _module_ dependency; this causes the rust driver
-* to locate an extern crate, scan its compilation metadata, and emit extern
-* declarations for any symbols used by the declaring crate.
-*
-* A "foreign" is an extern that references C (or other non-rust ABI) code.
-* There is no metadata to scan for extern references so in these cases either
-* a header-digester like bindgen, or manual function prototypes, have to
-* serve as declarators. So these are usually given explicitly as prototype
-* declarations, in rust code, with ABI attributes on them noting which ABI to
-* link via.
-*
-* An "upcall" is a foreign call generated by the compiler (not corresponding
-* to any user-written call in the code) into the runtime library, to perform
-* some helper task such as bringing a task to life, allocating memory, etc.
