Replace usages of 'bad_style' with 'nonstandard_style'.

Miri engine cleanup
* Unify the two maps in memory to store the allocation and its kind together.
* Share the handling of statics between CTFE and miri: The miri engine always
uses "lazy" `AllocType::Static` when encountering a static. Acessing that
static invokes CTFE (no matter the machine). The machine only has any
influence when writing to a static, which CTFE outright rejects (but miri
makes a copy-on-write).
* Add an `AllocId` to by-ref consts so miri can use them as operands without
making copies.
* Move responsibilities around for the `eval_fn_call` machine hook: The hook
just has to find the MIR (or entirely take care of everything); pushing the
new stack frame is taken care of by the miri engine.
* Expose the intrinsics and lang items implemented by CTFE so miri does not
have to reimplement them.
* Allow Machine to hook into foreign statics (used by miri to get rid of some other hacks).
* Clean up function calling.
* Switch const sanity check to work on operands, not mplaces.
* Move const_eval out of rustc_mir::interpret, to make sure that it does not access private implementation details.
In particular, we can finally make `eval_operand` take `&self`. :-)
Should be merged after https://github.com/rust-lang/rust/pull/53609, across which I will rebase.

move the Pin API into its own module for centralized documentation
This implements the change proposed by @withoutboats in #49150, as suggested by @RalfJung in the review of #53104,
along with the documentation that was originally in it, that was deemed more appropriate in module-level documentation.

Structs and enums can both be non-exhaustive, with a very different
meaning. This PR splits `is_non_exhaustive` to 2 separate functions - 1
for structs, and another for enums, and fixes the places that got the
usage confused.
Fixes #53549.

Fix #50865: ICE on impl-trait returning functions reaching private items
Adds a test case as suggested in #50865, and implements @petrochenkov's suggestion. Fixes #50865.
Impl-trait-returning functions are marked under a new (low) access level, which they propagate rather than `AccessLevels::Reachable`. `AccessLevels::is_reachable` returns false for such items (leaving stability analysis unaffected), these items may still be visible to the lints phase however.

Implement try block expressions
I noticed that `try` wasn't a keyword yet in Rust 2018, so...

Don't panic on std::env::vars() when env is null.
Fixes #53200.
Reviewer(s):
* Do I need to do any `#[cfg()]` here?
* Is this use of libc ok for a dev-dependency?

rustc_resolve: crates only exist in the type namespace.
Fixes #53333 by resolving `::crate_name` in `TypeNS` alone, which was overlooked in #52923 and didn't break tests, since having `use crate_name;` and a `crate_name` value in the same scope is rare.
