Rollup merge of #76973 - lzutao:unstably-const-assume, r=oli-obk
Unstably allow assume intrinsic in const contexts

Not sure much about this usage because there are concerns
about [blocking  optimization][1] and [slowing down LLVM][2] when using `assme` intrinsic
in inline functions.
But since Oli suggested in https://github.com/rust-lang/rust/issues/76960#issuecomment-695772221,
here we are.

Rollup merge of #76866 - est31:master, r=lcnr
Remove unused feature gates from library/ crates

Removes some unused feature gates from library crates. It's likely not a complete list as I only tested a subset for which it's more likely that it is unused.

baafc71f1f Remove unused libc feature gate
Libc isn't used by alloc.
And std and panic_* use libc from crates.io now,
which isn't feature gated.

41aaa90c67 Auto merge of #70212 - Amanieu:catch_foreign, r=Mark-Simulacrum
Abort when foreign exceptions are caught by catch_unwind

Prior to this PR, foreign exceptions were not caught by catch_unwind, and instead passed through invisibly. This represented a painful soundness hole in some libraries ([take_mut](https://github.com/Sgeo/take_mut/blob/master/src/lib.rs#L37)), which relied on `catch_unwind` to handle all possible exit paths from a closure.

With this PR, foreign exceptions are now caught by `catch_unwind` and will trigger an abort since catching foreign exceptions is currently UB according to the latest proposals by the FFI unwind project group.
