Fixes #93760

Emit an error instead of ICEing when an extern static's size overflows the allowed maximum for the target.

Changes the error message in the existing delay_span_bug call to the true layout error, first for debugging purposes, but opted to leave in to potentially assist future developers as it was being reached in unexpected ways already.

Seems to be a CI failure due to crates.io issues, will try later

Don't ICE when an extern static is too big for the current architecture

Fixes rust-lang#93760

Emit an error instead of ICEing when an `extern` static's size overflows the allowed maximum for the target.

Changes the error message in the existing `delay_span_bug` call to the true layout error, first for debugging purposes, but opted to leave in to potentially assist future developers as it was being reached in unexpected ways already.
