Steps to Reproduce and Observed Behavior

test {
    const not_merged = @as(error{ a, b, c, d, e, f, g, h }, undefined);
    const merged = @as(error{ a, b, c, d } || error{ e, f, g, h }, undefined);

    _ = not_merged;
    _ = merged;
}

the problem becomes much worse with many error types in the stdlib due to doc comments on each error

Expected Behavior

error set should be truncated similar to what was done in #1822
