Rollup merge of #77243 - Aaron1011:more-derive-test, r=petrochenkov
Test more attributes in test issue-75930-derive-cfg.rs

Split out from #76130

This tests our handling of combining derives, derive helper
attributes, attribute macros, and `cfg`/`cfg_attr`

pretty-print-reparse hack: Rename some variables for clarity

This will also make it easier to make the comparisons asymmetric.

Also one impossible case is removed.

Rollup merge of #77231 - oli-obk:clippy_const_fn, r=Manishearth
Move helper function for `missing_const_for_fn` out of rustc to clippy

cc @rust-lang/clippy @ecstatic-morse #76618

r? @Manishearth

I also removed all support for suggesting a function could be `const fn` when that would require feature gates to actually work.

This means we'll now have to maintain this ourselves in clippy, but that's how most lints work anyway, so...

Rollup merge of #77209 - jyn514:fix-docs, r=petrochenkov
Fix documentation highlighting in ty::BorrowKind

Previously it looked a little odd: https://doc.rust-lang.org/nightly/nightly-rustc/rustc_middle/ty/enum.BorrowKind.html#variant.UniqueImmBorrow

Noticed this while reviewing https://github.com/rust-lang/rustc-dev-guide/pull/894.

Rollup merge of #77208 - mati865:late-link-args-order, r=petrochenkov
Late link args order

MSYS2 changed how winpthreads is built and as the result it now depends on more mingw-w64 libraries.

This PR affects only MinGW targets since nobody else is using `late_link_args_{dynamic,static}`. Now the order is similar to how it used to be before https://github.com/rust-lang/rust/pull/67502.

Rollup merge of #77184 - pickfire:patch-4, r=kennytm
Rust vec bench import specific rand::RngCore

Using `RngCore` import for side effects is clearer than `*` which may bring it unnecessary more stuff than needed, it is also more explicit doing so.

@pickfire change `LEN = 16384` (and pos) and `once` instead of `[0].iter()` after this.

Rollup merge of #77107 - bugadani:perf, r=oli-obk
Enable const propagation into operands at mir_opt_level=2

Feature was added in #74507 but gated with `mir_opt_level>=3` because of compile time regressions. Let's see whether the LLVM 11 update solves that.

As the [perf results](https://github.com/rust-lang/rust/pull/77107#issuecomment-697668154) show, enabling this optimization results in a lot less regression as before.

623fb90b5a Auto merge of #76897 - Aaron1011:feature/min-proc-macro-metadata, r=petrochenkov
Encode less metadata for proc-macro crates

Currently, we serialize the same crate metadata for proc-macro crates as
we do for normal crates. This is quite wasteful - almost none of this
metadata is ever used, and much of it can't even be deserialized (if it
contains a foreign `CrateNum`).

This PR changes metadata encoding to skip encoding the majority of crate
metadata for proc-macro crates. Most of the `Lazy<[T]>` fields are left
completetly empty, while the non-lazy fields are left as-is.

Additionally, proc-macros now have a def span that does not include
their body. This was done for normal functions in #75465, but was missed
for proc-macros.

As a result of this PR, we should only ever encode local `CrateNum`s
when encoding proc-macro crates. I've added a specialized serialization
impl for `CrateNum` to assert this.

Rename `whence` to `span`

Rollup merge of #77161 - est31:swich_len_already_trusted, r=petrochenkov
Remove TrustedLen requirement from BuilderMethods::switch

The main use case of TrustedLen is allowing APIs to specialize on it,
but no use of it uses that specialization. Instead, only the .len()
function provided by ExactSizeIterator is used, which is already
required to be accurate.

Thus, the TrustedLen requirement on BuilderMethods::switch is redundant.

cc #76618

This is a template for splitting up `const_fn` into granular feature gates. I think this will make it easier, both for us and for users, to track stabilization of each individual feature. We don't *have* to do this, however. We could also keep stabilizing things out from under `const_fn`.
