4497196ba5 Auto merge of #37439 - michaelwoerister:remove-sha256, r=alexcrichton
Replace all uses of SHA-256 with BLAKE2b.

Removes the SHA-256 implementation and replaces all uses of it with BLAKE2b, which we already use for debuginfo type guids and incremental compilation hashes. It doesn't make much sense to have two different cryptographic hash implementations in the compiler and Blake has a few advantages over SHA-2 (computationally less expensive, hashes of up to 512 bits).

f5a702dc78 Auto merge of #37445 - nnethercote:shrink-Expr_, r=eddyb
Shrink Expr_::ExprInlineAsm.

On 64-bit this reduces the size of `Expr_` from 144 to 64 bytes, and
reduces the size of `Expr` from 176 to 96 bytes.

For the workload in #36799 this reduces the RSS for the "lowering ast -> hir" phase and all subsequent phases by 50 MiB, which reduces the peak RSS for that workload by about 1%. Not huge, but it's a very easy improvement.

aef5ca5590 Auto merge of #37392 - alexcrichton:more-disable-jemalloc, r=brson
Disable jemalloc on aarch64/powerpc

Sounds like jemalloc is broken on systems which differ in page size than the
host it was compiled on (unless an option was passed). This unfortunately
reduces the portability of binaries created and can often make Rust segfault by
default. For now let's patch over this by disabling jemalloc until we can figure
out a better solution.

Closes #36994

[2/n] rustc_metadata: move is_extern_item to trans.

*This is part of a series ([prev](https://github.com/rust-lang/rust/pull/37400) | [next](https://github.com/rust-lang/rust/pull/37402)) of patches designed to rework rustc into an out-of-order on-demand pipeline model for both better feature support (e.g. [MIR-based](https://github.com/solson/miri) early constant evaluation) and incremental execution of compiler passes (e.g. type-checking), with beneficial consequences to IDE support as well.
If any motivation is unclear, please ask for additional PR description clarifications or code comments.*
<hr>

Minor cleanup missed by #36551: `is_extern_item` is one of, if not the only `CrateStore` method who takes a `TyCtxt` but doesn't produce something cached in it, and such methods are going away.

[1/n] Move the MIR map into the type context.

*This is part of a series ([prev]() | [next](https://github.com/rust-lang/rust/pull/37401)) of patches designed to rework rustc into an out-of-order on-demand pipeline model for both better feature support (e.g. [MIR-based](https://github.com/solson/miri) early constant evaluation) and incremental execution of compiler passes (e.g. type-checking), with beneficial consequences to IDE support as well.
If any motivation is unclear, please ask for additional PR description clarifications or code comments.*
<hr>

The first commit reorganizes the `rustc::mir` module to contain the MIR types directly without an extraneous `repr` module which serves no practical purpose but is rather an eyesore.

The second commit performs the actual move of the MIR map into the type context, for the purposes of future integration with requesting analysis/lowering by-products through `TyCtxt`.

Local `Mir` bodies need to be mutated by passes (hence `RefCell`), and at least one pass (`qualify_consts`) needs simultaneous access to multiple `Mir` bodies (hence arena-allocation).
`Mir` bodies loaded from other crates appear as if immutably borrowed (by `.borrow()`-ing one `Ref` and subsequently "leaking" it) to avoid, at least dynamically, *any* possibility of their local mutation.

One caveat is that lint passes can now snoop at the MIR (helpful) or even mutate it (dangerous).
However, lints are unstable anyway and we can find a way to deal with this in due time.
Future work will result in a tighter API, potentially hiding mutation *completely* outside of MIR passes.

Prohibit patterns in trait methods without bodies

, mostly rejected by the parser already and generally don't make much sense.
This PR is kind of a missing part of https://github.com/rust-lang/rust/pull/35015.

Given the [statistics from crater](https://github.com/rust-lang/rust/pull/37378#issuecomment-256154994), the effect of this PR is mostly equivalent to improving `unused_mut` lint.
