Summary: GCC 5.1 began mangling these Windows calling conventions into function types, since they can be used for overloading. They've always been mangled in the MS ABI, but they are new to the Itanium mangler. Note that the calling convention doesn't appear as part of the main declaration, it only appears on function parameter types and other types. Fixes PR39860 Reviewers: rjmccall, efriedma Subscribers: cfe-commits Differential Revision: https://reviews.llvm.org/D55672 llvm-svn: 349212
