Tomasz Miąsko da9f3ec14e [Demangle][Rust] Parse dot suffix 
Allow mangled names to include an arbitrary dot suffix, akin to vendor
specific suffix in Itanium mangling.

Primary motivation is a support for symbols renamed during ThinLTO
import / promotion (ThinLTO is the default configuration for optimized
builds in rustc).
