NLL feature complete (adds `feature(nll)`)!
This is the final PR for the nll-master branch; it brings over all remaining content.
The contents of the branch include:
- track causal information and use it to report extended errors
- handle `impl Trait` in NLL code
- improve printing of outlives errors
- add `#![feature(nll)]` and some more sample tests
The commits should for the most part build independently.

In particular, -Znll might as well imply -Zborrowck=mir by default,
just like `#![feature(nll)]` does.
Also, if NLL is in use, no reason to emit end regions. The NLL pass
just strips them out anyway.
This is more convenient, and allows us to be more independent from
infcx, particularly with respect to `in_progress_tables` field.
No functional change.
Fix -Z lower_128bit_ops handling of statics
Avoids ICEs such as the following:

docs(slice): Clarification in binary_search_by
This PR ~fixes a small comment typo~ adds some clarification to a half-open interval in the `binary_search_by` function in `slice`.
Split PlaceContext::Store into Store & AsmOutput
Outputs in InlineAsm can be read-write, so splitting it out is useful for things like Store-Store folding, as that's unsound for a Store-AsmOutput.
This PR is intended to make no changes, just be the mechanical split of the enum. Future changes can use the split, like a MIR pass I'm working on and perhaps two-phase borrows (see this FIXME: https://github.com/rust-lang/rust/pull/46852/files#diff-74dcd7740ab2104cd2b9a3b68dd4f208R543)
Add Hash impl for SystemTime and Instant
Closes#46670.
Not sure how to actually test non-Linux platforms.
`rustc --target=i686-pc-windows-gnu --crate-name std --crate-type rlib src/libstd/lib.rs -o q.rlib` works a bit, but for Redox I'm not sure what to do.

Distribute intrinsic.natvis with the compiler for windows-msvc.
This adds `intrinsic.natvis` to the `windows-msvc` distributions of Rust, enabling the visualization of `str` and slices in the VS debugger. Two other natvis files are already included, this was probably just an oversight.
I also updated `rust-windbg.cmd` to load this file as well.
