If the sole distinction between two declarations is that one has a __restrict qualifier then we should not consider it to be an overload. Instead, we will consider it as an incompatible redeclaration which is similar to how MSVC, ICC and GCC would handle it. This fixes PR17786. N.B. We must not mangle in __restrict into method qualifiers becase we don't allow overloading between such declarations anymore. To do otherwise would be a violation of the Itanium ABI. llvm-svn: 193964
