Since libDemangling is included in the Swift standard library, ODR violations can occur on platforms that allow statically linking stdlib if Swift code is linked with other compiler libraries that also transitively pull in libDemangling, and if the stdlib version and compiler version do not match exactly (even down to commit drift between releases). This lets the runtime conditionally segregate its copies of the libDemangling symbols from those in the compiler using an inline namespace without affecting usage throughout source.
