Summary:
Try to skip running even `clang -###` when we know there's nothing to capture
in the clang command. Do that by recording in the `ClangCommand.t` whether the
command is pre- or post-running `clang -###`, and apply slightly different
filters in each case. In particular, the filter has to let in more commands
than necessary pre-`clang -###` because the flags are not normalised at that
point.
Also regard `-x cuda` commands as unsupported.

Summary:
- Rather than passing a directory name to PerfStats reporting api to write the stats to, and then determining the EventLogger `stats_type` from that dirname, there is now a `stats_type` type in PerfStats, and the directory name and EventLogger tag is automatically determined from that type after it is passed to the API
- This allows us to determine whether we're in capture mode or linters mode dynamically from PerfStats itself, and use the appropriate tag when creating an event

Summary:
Just a bunch of minor changes.
- The mutable field doesn't need to be mutable: it's only mutated once in the code somewhere that doesn't even need to mutate
- Hence the type can be public
- All the `ms_get_*` functions are replaced by field accesses
- `CMethod_signature` -> `CMethodSignature` while I'm at it, although maybe that's bad since other files in clang/ follow the former convention
- `type method_signature` -> `type t`
- `pp` function instead of `to_string`, since it's used with `fprintf`. This gets rid of the only caller of `IList.to_string`.

Summary:
Instead of storing the type environment in infer-out/captured/foo.c/foo.c.tenv,
store it in the `source_files` table of the SQLite db. This limits the number
of files we create on disk.
The "file local" type environemnts are specific to the clang integration. For
Java, there is a "global tenv" file. Instead of matching on string names, this
diff also makes the API of `Tenv` reflect this situation.
The global tenv is serialized as a separate file in "infer-out/.global.tenv"
instead of "infer-out/captured/global.tenv", because "infer-out/captured/" will
soon be removed as it now only contains the global tenv (except in debug mode,
where it will still be created).
In the DB, we either store the local tenv for the file, or "global" to indicate
that the global tenv should be consulted.
This diff also moves `Cfg.store` to `SourceFiles.add` because that function
deals with more than just `Cfg.t`.

Summary: We do not inject a destructor call if the destructor declaration does not contain a body in AST. We miss all the cases where the destructor is declared in `.h` file and defined in `.cpp` file as other files include `.h` file and do not contain the body of the destructor when destructor calls are being injected based on AST information. After this diff we inject destructor calls even if we do not have body for the destructor in AST.

Summary: In Obj-C blocks, we explicitly insert reads of the captured vars. This does the same thing for C++. For example, `foo() { int x = 1; [x]() { return x; } }` would previously not contain a read of `x` in `foo`. Now, we'll create a temporary that reads from `x` and pass it to the closure value.

Summary:
In some cases infer runs clang commands where we do not attach the plugin,
notably for pre-processor-only commands like `clang -E foo.c`. Usually these
commands are used by build systems to test their output, so infer should not
swallow it.
This makes infer echo the stdout of clang whenever we do not attach the plugin
to clang. When the plugin is attached, stdout is captured because that's where
the plugin outputs its results, so we cannot do the same in this case (not that
we would want to yet).
Fixes#696.
