compiler: Include span of too huge array with `-Cdebuginfo=2` We have a few ui tests to ensure we emit an error if we encounter too big arrays. Before this fix, compiling the tests with `-Cdebuginfo=2` would not include the spans of the instantiation sites, because the error is then emitted from a different code path that does not include the span. Propagate the span to the error also in the debuginfo case, so the tests passes regardless of debuginfo level. r? ``@wesleywiser`` since this is a natural continuation of https://github.com/rust-lang/rust/pull/145967 that you approved (thanks!). cc https://github.com/rust-lang/rust/issues/61117 since this takes is one step closer to increasing `rust.debuginfo-level-tests` to `2` in the **x86_64-gnu-debug** CI job. ## Test failure output without the fix <details> <summary> Here is what the test failures look like if you run the tests without the fix.

This is the main source code repository for Rust. It contains the compiler, standard library, and documentation.
Why Rust?
-
Performance: Fast and memory-efficient, suitable for critical services, embedded devices, and easily integrated with other languages.
-
Reliability: Our rich type system and ownership model ensure memory and thread safety, reducing bugs at compile-time.
-
Productivity: Comprehensive documentation, a compiler committed to providing great diagnostics, and advanced tooling including package manager and build tool (Cargo), auto-formatter (rustfmt), linter (Clippy) and editor support (rust-analyzer).
