Fix spurious test failure with `panic=abort`

Description on why it happens and why the fix should work is in the code comments.

Bubble up nested goals from equation in `predicates_for_object_candidate`

This used to be needed for rust-lang#114036 (comment), but since it's no longer, I'm opening this as a separate PR. This also fixes one ICEing UI test: (`tests/ui/unboxed-closures/issue-53448.rs`)

Add trait decls to SMIR

Closes rust-lang/project-stable-mir#20

Set max_atomic_width for AVR to 16

This is currently set to 0

https://github.com/rust-lang/rust/blob/90f0b24ad3e7fc0dc0e419c9da30d74629cd5736/compiler/rustc_target/src/spec/avr_gnu_base.rs#L26-L27

However, LLVM supports {8,16}-bit atomic load/store on AVR (support for RMW is still quite incomplete and only partially supported).

Set max_atomic_width for sparc-unknown-linux-gnu to 32

This is currently set to 64

https://github.com/rust-lang/rust/blob/90f0b24ad3e7fc0dc0e419c9da30d74629cd5736/compiler/rustc_target/src/spec/sparc_unknown_linux_gnu.rs#L8

However, AFAIK, this architecture doesn't support 64-bit atomics, and LLVM generates libcalls: https://godbolt.org/z/chzThWGG1

(Currently, attempts to run `cargo test` for this target result in "undefined reference to `__sync_val_compare_and_swap_8'" error. taiki-e/rust-cross-toolchain@02efe1e)

stabilize abi_thiscall

Closes rust-lang#42202, stabilizing the use of the "thiscall" ABI.

FCP was substituted by a poll, and the poll has been accepted.

CI: do not hide error logs in a group

This PR avoids creating a GHA group at the very end of a CI workflow when some failure has happened. Before, when a failure has happened, its GHA group was not closed, however the clock drift check function would create a new group, which would actually close the group containing the error log, thus making errors hidden by default, which is not ideal.
