ld.lld: warning <internal>:(.eh_frame) is being placed in ‘.eh_frame’

Similar to #1012, but this time, in samples/rust/rust_echo_server.rs in the rust branch.
See: #355.

This is probably the one that Wedson noticed back then, and it is unrelated to the version upgrade -- I am removing the version from the title.

@ojeda ojeda changed the title .eh_frame section emitted for rust_echo_server.o (rustc >= 1.70.0) .eh_frame section emitted for rust_echo_server.o Jun 21, 2023

Add MIR validation for unwind out from nounwind functions + fixes to make validation pass

`@Nilstrieb`  This is the MIR validation you asked in rust-lang#112403 (comment).

Two passes need to be fixed to get the validation to pass:
* `RemoveNoopLandingPads` currently unconditionally introduce a resume block (even there is none to begin with!), changed to not do that
* Generator state transform introduces a `assert` which may unwind, and its drop elaboration also introduces many new `UnwindAction`s, so in this case run the AbortUnwindingCalls after the transformation.

I believe this PR should also fix Rust-for-Linux/linux#1016, cc `@ojeda`

Fix merged for Rust 1.73.0. Thanks @nbdd0121! I will test it with a future nightly to see if it fixes it.
