Implemented SV-COMP 2016 runtime functions which can be activated with

the --svcomp-runtime flag. This is accompanied with a set of tests
to check all the functions are callable.

Due to the fact that the SV-COMP benchmark suite contains a mixture
of i386 and x86_64 benchmarks it is necessary to compile the runtime
functions twice, once for i386 and once for x86_64 and then link the
right version in at runtime. An example function that is problematic
is ``__VERIFIER_nondet_long()`` which is a different size on i386
and x86_64.
