Clang currently crashes on
class C {
C() = default;
C() = delete;
};
My cunning plan for fixing this was to change the `if (!FnD)` in
Parser::ParseCXXInlineMethodDef() to `if (!FnD || FnD->isInvalidDecl)` – but
alas, the second constructor decl wasn't marked as invalid. This lets
Sema::MergeFunctionDecl() return true on function redeclarations, which leads
to them being marked invalid.
This also improves error messages when functions are redeclared.
