Subject: [PATCH 5/7] Use Alloc and Layout from core::heap.

94d1970bba87f2d2893f6e934e4c3f02ed50604d moved the alloc::allocator
module to core::heap, moving e.g. Alloc and Layout out of the alloc
crate. While alloc::heap reexports them, it's better to use them from
where they really come from.

Subject: [PATCH 7/7] Bump to 1.27.0

Also update some `Cargo.lock` dependencies, finishing up some final steps of our
[release process]!

This doesn't update the bootstrap compiler just yet but that will come in a
follow-up PR.

[release process]: https://forge.rust-lang.org/release-process.html
