Some functions/classes have renamed while the comments still use the old names. Delete them per coding style.
Also some whitespace cleanup.

This is to support some analyses, like -Wunreachable-code, that
will need to recover the original unprunned CFG edges in order
to suppress issues that aren't really bugs in practice.
There are two important changes here:
- AdjacentBlock replaces CFGBlock* for CFG successors/predecessors.
This has the size of 2 pointers, instead of 1. This is unlikely
to have a significant memory impact on Sema since a single
CFG usually exists at one time, but could impact the memory
usage of the static analyzer. This could possibly be optimized
down to a single pointer with some cleverness.
- Predecessors can now contain null predecessors, which means
some analyses doing a reverse traversal will need to take into
account. This already exists for successors, which contain
successor slots for specific branch kinds (e.g., 'if') that
expect a fixed number of successors, even if a branch is
not reachable.

This rename serves two purposes:
- It reflects the actual functionality of this analysis.
- We will have more than one reachability analysis.
