Previously, we would translate `throw` with `return`. However, `throw` in

1. Attempt to simplify callExpr_trans by merging multiple if-else branches into one in `CTrans_utils.builtin_trans`. Not every special case works that way, so some of them are still there.
2. On top of that, make type of parameters in `CTrans_models` functions `Procname.t` instead `Procname.t option`. This triggered some more changes to `callExpr_trans`.
3. Semi-randomly reorder instructions in `callExpr_trans`
This is mainly an attempt to clean up the code so any suggestions how to make it better are welcome.

Since clang -### can silently return nothing when passed bogus arguments (eg,

in case it's a genuine error. This prevents puzzling behaviours such as

Class names fragile, easy to break and they introduce another level of indirection.
Since C++ translation doesn't need names, pass decl pointers everywhere.
Doing otherwise will most likely result in assert false.
Handling of class names in objc translation is more involving and it's left
for now. Later, objc can use same mechanism as C++.

Summary:
This diff changes the toplevel 'infer' executable from the current
python script to an OCaml binary. Currently this executable only parses
command line arguments, sets up environment variables, and invokes the
existing python script. This improves infer's command-line and
configuration interface, since passing arguments to the frontends or
backend no longer requires manually setting environment variables, and
arguments for the toplevel can now also be specified in .inferconfig.
Simplification and migration of functionality from the python script is
left for the future.
