Optimizing C++ Const Objects in LLVM

Can you link to more information about this? Googling for "c++ core lifetime profile" just takes me to the Core Guidelines.

Is the idea that they'll codify a bunch of static analysis that disallows problematic constructs & patterns? Could implementers then add something like Rust's ownership checks (assuming full source visibility)?

My sibling commentators have given you good links, but it's worth noting that these systems and Rust have a lot of differences. For example, they're explicitly not trying to tackle data races, and the way that they work is different.

I'm excited to see this all play out though!

Yes.

Microsoft has delivered a beta version of it with VS 2015 Update 1.

Clang guys are improving clang-tidy for similar errors.

Check Herb Sutter's talk at CppCon 2015.
