[turbofan] Introduce JSToInteger and JSToLength operators.

These operators will be easier to optimize, and we can remove some
unnecessary clutter from the intrinsic lowering.

Drive-by-cleanup: Some alpha sorting of the type conversion operator
business.

Hey Michi,

Here's a simple refactoring to reduce the clutter in JSIntrinsicLowering and

Please take a look.

Thanks,
Benedikt
