Summary:
This diff `#define`s the functions to which `assert` compiles to
`abort`. This enables the analyzer to report assertion violations, and
is independent of platform.
Also add a simple test to check that it is detected correctly.

Summary:
Currently there is a symbolic execution option to ignore exceptional
control flow. This hack does not fit well, and it is unclear how much
backend functionality should take it into consideration. This diff
removes this option and replaces it with an option during model
compilation. This has the advantage of clarifying and simplifying the
backend, with the disadvantage of no longer supporting switching
between exceptions and no-exceptions modes at analysis time. Since the
possibility of ignoring exceptional control flow is due to it not being
ready yet, this is a good trade to make.

Summary:
This diff adds a `__llair_alloc` intrinsic which is modeled
as a non-failing malloc. Using it instead of `malloc` increases
the readbility of symbolic heaps, because it removes all the cases
where malloc failed.
Note that `assert(malloc())` does not have the desired effect.

Summary:
Make could get confused and use both the $(MODEL_DIR)/cxxabi.bc and
%.bc rules, leading to build failure.
