Summary:
This simplifies the frontends and backends in most cases. Before this diff,
returning `void` could be modelled either with a `None` return, or a dummy
return variable with type `Tvoid`. Now it's always the latter.

Summary:
The abstract interpreter tried to handle exceptional control-flow by propagating the *pre* of a block that threw an exception rather than the *post*.
This was a half-measure that isn't correct when an exception-throwing instruction isn't in the middle of a block.
The handling of exceptions wasn't actually used anywhere and was leading to further hacks in `ProcCfg`, so let's get rid of it.

Summary:
Previously, the command parsing code filtered out any elements that were `False`y in the Python sense (starting with D5507925).
This meant that a command like `javac -classpath '' -Xmaxerrs 1000 MyFile.java` would be parsed as `javac -classpath -Xmaxerrs 1000 MyFile.java`, which will fail with "unrecognized option 1000".
This diff removes the filtering and fixes that issue.

Summary:
Add a `--source-files` option to `infer explore` to print information about the source files captured by infer.
More precisely, `infer explore --source-files` will print each row of the "source_files" table in the results database.
Option `--source-files-filter` can be used to filter output to file names matching an SQLite "LIKE" pattern.
Flags `--source-files-cfgs`, `--source-files-type-environment`, `--source-files-procedure-names` and `--source-files-freshly-captured` control which columns to print.
The printers for some existing types have been tweaked to improve the output.

When looking at large CFGs, at least in `xdot`, it's often difficult to find
the procedure you're looking for. Sorting the proc names puts them in

[This is a stepping stone before moving the specs data to sqlite.]
Previously, things worked like this (ignore ObjC):
1. capture & analyse C models
2. capture & analyse C++ models
3. copy C *.specs files to lib/specs/
4. copy C++ *.specs files to lib/specs/
Now it works like this:
1. capture C models
2. capture C++ models
3. analyse both together
4. install *.specs files to lib/specs

We were using the "filename" as the key because it's (kinda) unique *and* human
readable, but with the `infer explore --procedures` interface we don't really
need the human readable part anymore, so we can just use the OCaml marshalling
of the pname as the key. The human-readable version (sans unique-fying hash) is
now another column in the table, used to match procedure names in
`--procedures-filter`.
