77c283465c Also test for undef in enum discriminant 
The error message is sub-par, but fixing that requries moving ScalarMaybeUndef
to librustc which would conflict badly with another PR that is in flight.

Remove checks for LLVM < 4.0

While we still have to support LLVM 4.0 for Emscripten, we can drop checks for LLVM >= 4.0 and < 4.0.

e6c5cf9234 Auto merge of #55665 - eddyb:by-ref-layout-of, r=oli-obk 
rustc_target: pass contexts by reference, not value.

`LayoutOf` now takes `&self` instead of `self`, and so does every method generic over a context that implements `LayoutOf` and/or other traits, like `HasDataLayout`, `HasTyCtxt`, etc.

Originally using by-value `Copy` types was relevant because `TyCtxt` was one of those types, but now `TyCtxt::layout_of` is separate from `LayoutOf`, and `TyCtxt` is not an often used layout context.

Passing these context by reference is a lot nicer for miri, which has `self: &mut EvalContext`, and needed `f(&self)` (that is, creating `&&mut EvalContext` references) for layout purposes.
Now, the `&mut EvalContext` can be passed to a function expecting `&C`, directly.

This should help with #54012 / #55627 (to not need `where &'a T::Cx: LayoutOf` bounds).

b6e8f9dbdc Auto merge of #55238 - alexcrichton:rm-jemalloc, r=estebank 
Remove the `alloc_jemalloc` crate

This commit removes the `alloc_jemalloc` crate from the standard library and all related configuration. We will no longer be shipping this unstable crate. Rationale for this is provided on https://github.com/rust-lang/rust/issues/36963 and the many linked issues, but I can inline rationale here if desired!

We currently rely on jemalloc for increased perf in the Rust compiler, however. [This perf run shows](https://perf.rust-lang.org/compare.html?start=74ff7dcb1388e60a613cd6050bcd372a3cc4998b&end=7e7928dc0340d79b404e93f0c79eb4b946c1d669&stat=wall-time) that if we switch to glibc 2.23's allocator that it's slower than jemalloc across many benchmarks. [This perf run, however](https://perf.rust-lang.org/compare.html?start=22cc2ae8057d14e980b7c784e1eb2eee26b59e7d&end=10c95ccfa7a7adc12f4e608621ca29f9b98eed29), shows that if we use `jemalloc-sys` from crates.io then rustc actually gets faster across all benchmarks! (presumably because it has a more recent version of jemalloc than our submodule).

As a result, it's expected that this doesn't regress any code (as it's just removing an unstable crate) and it should actually improve rustc performance because it updates jemalloc.

Closes #36963

757d6cc91a Auto merge of #55363 - pietroalbini:update-cargo-vendor, r=Mark-Simulacrum 
Bump cargo-vendor version

Currently we pin `cargo-vendor` to 0.1.4, which doesn't set the `User-Agent` HTTP header. crates.io is going to require that header in the near future, so this PR bumps the pinned version of the crate to the latest one (which correctly sets the header).
