stage2: Panic when instantiating generic function with tuple

[topolarity]

Zig Version

0.10.0-dev.3363+0fc79d602

Steps to Reproduce

fn pair(x: f32, y: f32) std.meta.Tuple(&.{f32, f32}) {
    return .{ x, y };
}

fn foo(_: anytype) void {}

test {
    const x = comptime pair(1.5, 2.5);
    foo(.{ x });
}

Expected Behavior

Test should pass, compiler should not panic

Actual Behavior

thread 13494 panic: reached unreachable code
