Fix ICE when using zero-length SIMD type in extern static before my fix using a zero-length SIMD type in an extern static would cause an internal compiler error. now it properly shows a diagnostic error instead of panicking. it was because `LayoutError::InvalidSimd` wasn't handled in `check_static_inhabited` and fell through to a generic `delayed_bug`. i added handling for `InvalidSimd` in `check_static_inhabited` (similar to `SizeOverflow`): when a SIMD type has an invalid layout, we call `emit_err` with `Spanned` to emit a normal error instead of an ICE. compiler now emits a clear error `"the SIMD type Simd<u8, 0> has zero elements"` with the correct span on the type, matching expected compiler behavior. fixes rust-lang/rust#151451
