Rename front end shadow classes from "Kernel..." to "Shadow...".

Rename front end shadow classes from "Kernel..." to "Shadow...".

This should reduce confusion, since these classes are specifically
*not* part of kernel.  I also went ahead and renamed a few classes
that aren't shadow classes but are related to the shadow classes,
e.g. KernelTypeInferrer -> ShadowTypeInferrer.

This is a big CL but hopefully any merge conflicts it introduces should be easy
to resolve, since it's just a bulk rename.

Thank you. I'm glad I was *thinking* about how to implement patching yesterday,
so I'm not impacted by this rename :-)
