const-eval: make misalignment a hard error

It's been a future-incompat error (showing up in cargo's reports) since https://github.com/rust-lang/rust/pull/104616, Rust 1.68, released in March.  That should be long enough.

The question for the lang team is simply -- should we move ahead with this, making const-eval alignment failures a hard error? (It turns out some of them accidentally already were hard errors since #104616. But not all so this is still a breaking change. Crater found no regression.)

8fa7bdf191 Auto merge of #115670 - Zoxc:outline-panic-macro-1, r=Mark-Simulacrum
Partially outline code inside the panic! macro

This outlines code inside the panic! macro in some cases. This is split out from https://github.com/rust-lang/rust/pull/115562 to exclude changes to rustc.

67f455afe1 Suppress "erroneous constant used" for constants tainted by errors
When constant evaluation fails because its MIR is tainted by errors,
suppress note indicating that erroneous constant was used, since those
errors have to be fixed regardless of the constant being used or not.

05a665f21a Lower intrinsics::offset to mir::BinOp::Offset
They're semantically the same, so this means the backends don't need to handle the intrinsic and means fewer MIR basic blocks in pointer arithmetic code.

38b7cdf393 Use target instead of machine for mir interpreter integer handling.
The naming of `machine` only makes sense from a mir interpreter internals perspective, but outside users talk about the `target` platform

eea42733ac Replace terminator-based const eval limit
- Remove logic that limits const eval based on terminators, and use the
  stable metric instead (back edges + fn calls)
- Add unstable flag `tiny-const-eval-limit` to add UI tests that do not
  have to go up to the regular 2M step limit

360db516cc Create stable metric to measure long computation in Const Eval
This patch adds a `MirPass` that tracks the number of back-edges and
function calls in the CFG, adds a new MIR instruction to increment a
counter every time they are encountered during Const Eval, and emit a
warning if a configured limit is breached.

Switching them to `Break(())` and `Continue(())` instead.
