NodeBuilder should not assume it's dealing with a single predecessor. Remove predecessor getters. Modify the BranchNodeBuilder to not be responsible for doing auto-transitions (which depend on a predecessor).

It now only depends on a generic NodeBuilder instead. As part of this change, make the generic node builder results finalized by default.

Take advantage of the new builders for branch processing. As part of this change pass generic NodeBuilder (instead of BranchNodeBuilder) to the BranchCondition callback and remove the unused methods form BranchBuilder.

Each builder will have a different one, so it doesn't make sense to keep it in the context.

[analyzer] Node Builder refactoring: Introduce a simple Node Builder responsible for generating the node frontier.

Currently we have a bunch of different node builders which provide some common
functionality but are difficult to refactor. Each builder generates nodes of
different kinds and calculates the frontier nodes, which should be propagated
to the next step (after the builder dies).

Introduce a new NodeBuilder which provides very basic node generation facilities
but takes care of the second problem. The idea is that all the other builders
will eventually use it. Use this builder in CheckerContext instead of
StmtNodeBuilder (the way the frontier is propagated to the StmtBuilder
is a hack and will be removed later on).
