WebKit::nsTextAlignmentFromTextAlignment() falls through ASSERT_NOT_REACHED().

In the `default` case, `nsTextAlignment` is returned uninitialized.

static NSTextAlignment nsTextAlignmentFromTextAlignment(TextAlignment textAlignment)
{   
    NSTextAlignment nsTextAlignment;
    switch (textAlignment) {
    case NoAlignment:
        nsTextAlignment = NSTextAlignmentNatural;
        break;
    case LeftAlignment: 
        nsTextAlignment = NSTextAlignmentLeft;
        break;
    case RightAlignment:
        nsTextAlignment = NSTextAlignmentRight;
        break;
    case CenterAlignment: 
        nsTextAlignment = NSTextAlignmentCenter;
        break;
    case JustifiedAlignment:
        nsTextAlignment = NSTextAlignmentJustified;
        break;
    default:
        ASSERT_NOT_REACHED();
    }
    
    return nsTextAlignment;
}
