ExplodedGraph nodes will now have a numeric identifier stored in them
which will keep track of the order in which the nodes were created
and it will be fully deterministic both accross runs and across machines.
This is extremely useful for debugging as it allows reliably setting
conditional breakpoints by node IDs.

Because cast expressions have their own hierarchy, it's extremely useful
to have some information about what kind of casts are we dealing with.

- Correctly display macro expansion and spelling locations.
- Use the same procedure to display location context call site locations.
- Display statement IDs for program points.

Add a label to nodes that have a bug report attached or on which
the analysis was generally interrupted.
Fix printing has_report and implement printing is_sink in the graph dumper.

When printing various statements that include braces (compound
statements, lambda expressions, statement-expressions, etc.),
replace the code between braces with '...'.

In this mode the tool would avoid duplicating the contents of the
program state on every node, replacing them with a diff-like dump
of changes that happened on that node.
This is useful because most of the time we only interested in whether
the effect of the statement was modeled correctly. A diffed graph would
also be much faster to load and navigate, being much smaller than
the original graph.
The diffs are computed "semantically" as opposed to plain text diffs.
I.e., the diff algorithm is hand-crafted separately for every state trait,
taking the underlying data structures into account. This is especially nice
for Environment because textual diffs would have been terrible.
On the other hand, it requires some boilerplate to implement.

This is a utility to improve readability and generally manipulate
GraphViz dumps of the analysis graph. Such dumps are often huge and
not only hard to read, but also often hang the viewer apps with their
mere size. Such script should significantly improve debugging experience.
