It turns out I misunderstood how this release process works; it is _only_ important inside our internal test harness, not inside the LLVM public test harness; I apologize for opening this non-useful PR.

oops, missed a commit (ignore)

Fix the code to work with built-in lit/main.py

(ping; I'd like to get this reviewed so that we can merge it at the same time into public LLVM as into MSVC's version)

Attempting to add more metadata

Some minor nits, mostly.

minor naming change

Add interceptors for the debug runtime on x86

We can go back and do a formatting pass later, all the actual code looks correct to me though.

This is no longer necessary, as llvm::is_trivially_copyable no longer exists; closing the bugs.

Probably good to rename the title as well.

Given that the MSVC-STL team is planning on backporting this fix to C++14 (the earliest supported version), I think it's reasonable to backport this to at least C++11 (see the comment thread).

Yeah I dunno what's happening here.

Adding the two people who implemented the function.

Just for you @CaseyCarter :) (thanks!)
