Patch to mangle __uuidof expressions under -fms-extensions

[Reid Kleckner]

+        // This CXXUuidofExpr is mangled as-if it were actually a VarDecl
from
+        // const __s_GUID _GUID_{lower case UUID with underscores}
+        StringRef Uuid = UE->getUuidAsStringRef(Context.getASTContext());
+        std::string Name = "_GUID_" + Uuid.lower();
+        std::replace(Name.begin(), Name.end(), '-', '_');
+        Out << "$E?";
+        Out << Name << "@@3U__s_GUID@@B";

We should give this a name consistent with Itanium like "__uuidof_" + Name.
