ac19c3bda1 Auto merge of #76856 - jonas-schievink:dist-rustc-src, r=Mark-Simulacrum 
Distribute rustc sources as part of `rustc-dev`

They can be used to provide IDE features when working on rustc plugins/backends/etc without having to locate a separate Rust checkout.

88538adf9a Record intra-statement/terminator conflicts 
Some MIR statements and terminators have an (undocumented...) invariant
that some of their input and outputs must not overlap. This records
conflicts between locals used in these positions.

2cbc570e58 Auto merge of #76884 - Mark-Simulacrum:fix-macos-ci, r=pietroalbini 
Add host triples to target lists

This PR is primarily intended to fix https://github.com/rust-lang/rustup/issues/2494, which is the second commit. That bug was introduced by #76415, and incompletely fixed by #76639. (#76639 added host triples, which gave us compilers, but missed that we also need documentation and other target-only things). However, it also removes duplicate macOS CI builders.

9f8ac718f4 Auto merge of #76575 - lcnr:abstract-const, r=oli-obk 
compare generic constants using `AbstractConst`s

This is a MVP of rust-lang/compiler-team#340. The changes in this PR should only be relevant if `feature(const_evaluatable_checked)` is enabled.

~~currently based on top of #76559, so blocked on that.~~

Wrap recursive predicate evaluation with ensure_sufficient_stack 
I haven't been able to come up with a minimized test case for #76770,
but this fixes a stack overflow in rustc as well.
