03b562aecb Tighten up SparcV9FloatCCRegClass::getRegName()'s assertion - if you ask it for 
the name of %fsr (as the comment in SparcV9RegClassInfo.h used to suggest)
you would walk off the end of the FloatCCRegName array.

de4803d0af As per Chris, greatly simplify handling of external functions by using the 
wrapper idea uniformly: we can use Value::replaceAllUsesWith() instead of
special-casing by class of user.

dc7fef83dc 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.

cc43909bb6 If the preheader of the loop was the entry block of the function, make sure 
that the exit block of the loop becomes the new entry block of the function.

50ca0a195a 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.
