Show line of references when compilation fails

Zig Version

0.14.0-dev.32+4aa15440c

Steps to Reproduce and Observed Output

fn someFunc(a: anytype) void {
    if (@TypeOf(a) != i32) {
        @compileError("you can't do this!");
    }
}

fn someFunc2(a: anytype) void {
    someFunc(a);
}

pub fn main() void {
    someFunc2(1.1);
}

This code fails to compile with this message:

❯ zig build
install
└─ install exp-zig
   └─ zig build-exe exp-zig Debug native 1 errors
src/main.zig:3:9: error: you can't do this!
        @compileError("you can't do this!");
        ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
referenced by:
    someFunc2__anon_3324: src/main.zig:8:13
    main: src/main.zig:12:14
    remaining reference traces hidden; use '-freference-trace' to see all reference traces

All necessary information is there. However the important part is where it is being called from: someFunc(1.1);
I think showing the line of references should help developers.

Expected Output

❯ zig build
install
└─ install exp-zig
   └─ zig build-exe exp-zig Debug native 1 errors
src/main.zig:3:9: error: you can't do this!
        @compileError("you can't do this!");

I think this issue can be closed if it's considered duplicate of: #20294 (comment)

[Vexu]

The lines are intentionally not included to reduce noise in the output but could be added if -freference-trace is specified.

[Not-Nik]

Maybe this can be specifically enabled in the @compileError, maybe with a .TraceCall or similar.
