debug info regression

[nektro]

Zig Version

0.10.0-dev.2998+a45592715

Steps to Reproduce

the following code tries to produce an enum with undefined fields and produces an ICE

const std = @import("std");

test {
    comptime var fields: [2]std.builtin.Type.EnumField = undefined;
    _ = @Type(.{ .Enum = .{
        .layout = .Auto,
        .tag_type = u1,
        .fields = &fields,
        .decls = &.{},
        .is_exhaustive = true,
    } });
}

Expected Behavior

proper line info for all stack trace items

Actual Behavior

line info missing in cpp code

Duplicate of #11981.

[nektro]

the compiler crash isnt what the issue is about

[Vexu]

In that case it might be duplicate of #12120

[Vexu]

Stage1 has been deleted and I get a proper stack trace from the stage2 crash.
