Eric Fiselier 3c35491f02 Update all bug URL's to point to https://bugs.llvm.org/...

Eric Fiselier a18ef6f1f9 Fix PR31916 - std::visit rejects visitors accepting lvalue arguments 
A static assertion was misfiring since it checked
is_callable<Visitor, decltype(__variant_alt<T>.value)>. However
the decltype expression doesn't capture the value category as
required. This patch applies extra braces to decltype to fix
that.

Eric Fiselier f9127593a9 Implement P0513R0 - "Poisoning the Hash" 
Summary:
Exactly what the title says.

This patch also adds a `std::hash<nullptr_t>` specialization in C++17, but it was not added by this paper and I can't find the actual paper that adds it.

See http://wg21.link/P0513R0 for more info.

If there are no comments in the next couple of days I'll commit this

Michael Park f4770ea983 Added a workaround for a `-fdelayed-template-parsing` bug. 
Summary:
There seems to be an additional bug in `-fdelayed-template-parsing`
similar to
http://llvm.org/viewvc/llvm-project?view=revision&revision=236063.

This is a workaround for it for <variant> to compile with `clang-cl` on Windows.
