Optimize dropck This does two things: caches the `trivial_dropck` check by making it a query, and shifts around the implementation of the primary dropck itself to avoid allocating many small vectors.

fmt::Write is about string slices, not byte slices No idea why the docs talk about bytes, maybe a copy-paste error?

add example for type_name So users of this function could at least expect what its output for current compiler version.

Don't recommend ONCE_INIT in std::sync::Once ONCE_INIT is deprecated, and so suggesting it as not only being on par with, but before `Once::new` is a bad idea.

InterpCx: make memory field public I made this field private forever ago because I thought sealing things might be nice. But with the `memory_mut` getter it doesn't actually seal anything, and it's not like we need to invalidate caches on writes to memory or so. And moreover, having to use the getters leads to some annoying borrow checking interactions. So, let's just make it public (again). r? @oli-obk

make File::try_clone produce non-inheritable handles on Windows ~**NOT READY FOR REVIEW.** This PR is currently mainly to trigger CI so that I can see what happens. (Is there a better way to trigger CI?) I don't know whether this change makes sense yet.~ (Edit: @Mark-Simulacrum clarified that CI doesn't currently run on Windows.) --- File handles shouldn't be inheritable in general. `std::process::Command` takes care of making them inheritable when child processes are spawned, and the `CREATE_PROCESS_LOCK` protects against races in that section on Windows. But `File::try_clone` has been creating inheritable file descriptors outside of that lock, which could be leaking into other child processes unintentionally. See also https://github.com/rust-lang/rust/pull/31069#discussion_r334117665.

Move debug_map assertions after check for err Fixes #65231 We have some assertions in `DebugMap` to catch broken implementations of `Debug` that produce malformed entries. These checks don't make sense if formatting fails partway through. This PR moves those assertions to within the `and_then` closures along with the other formatting logic, so they're only checked if the map hasn't failed to format an entry already.

rustc_metadata: replace Entry table with one table for each of its fields (AoS -> SoA). In https://github.com/rust-lang/rust/pull/59789#issuecomment-481958212 I noticed that for many cross-crate queries (e.g. `predicates_of(def_id)`), we were deserializing the `rustc_metadata::schema::Entry` for `def_id` *only* to read one field (i.e. `predicates`). But there are several such queries, and `Entry` is not particularly small (in terms of number of fields, the encoding itself is quite compact), so there is a large (and unnecessary) constant factor. This PR replaces the (random-access) array¹ of `Entry` structures ("AoS"), with many separate arrays¹, one for each field that used to be in `Entry` ("SoA"), resulting in the ability to read individual fields separately, with negligible time overhead (in thoery), and some size overhead (as these arrays are not sparse). In a way, the new approach is closer to incremental on-disk caches, which store each query's cached results separately, but it would take significantly more work to unify the two. For stage1 `libcore`'s metadata blob, the size overhead is `8.44%`, and I have another commit (~~not initially included because I want to do perf runs with both~~ **EDIT**: added it now) that brings it down to `5.88%`. ¹(in the source, these arrays are called "tables", but perhaps they could use a better name)

Upgrade Emscripten targets to use upstream LLVM backend - Compatible with Emscripten 1.38.46-upstream or later upstream. - Refactors the Emscripten target spec to share code with other wasm targets. - Replaces the old incorrect wasm32 C call ABI with the correct one, preserving the old one as wasm32_bindgen_compat for wasm-bindgen compatibility. - Updates the varargs ABI used by Emscripten and deletes the old one. - Removes the obsolete wasm32-experimental-emscripten target. - Uses EMCC_CFLAGS on CI to avoid the timeout problems with #63649. r? @alexcrichton

use precalculated dominators in explain_borrow This looks like the only place calculating dominators from the MIR body every time instead of using the ones stored on the `MirBorrowckCtxt`. For example, in rust-lang/rust#65131 a big generated function with a number of borrowck errors takes a few hours(!) recalculating the dominators while explaining the errors. I don't know enough about this part of rustc codebase to know for sure that this change is correct, but no tests seem to fail as a result of this change in local testing.
