Finally implement rewriting global initializers which use external functions
...
by creating an internal wrapper function with same signature as the external
function, and use it instead of the "real" function.
The wrapper then calls the external function using the same JIT function
resolution API that has been used before for rewriting instructions, since the
wrapper has an explicit call instruction which we can rewrite.

After unrolling our single basic block loop, fold it into the preheader and exit
...
block. The primary motivation for doing this is that we can now unroll nested loops.
This makes a pretty big difference in some cases. For example, in 183.equake,
we are now beating the native compiler with the CBE, and we are a lot closer
with LLC.
I'm now going to play around a bit with the unroll factor and see what effect
it really has.
