capitalize Option per LLVM coding conventions

Done.

I think it would be better to have a single getRandomizeImmediates() method
instead of a bunch of bool getters.  There are other getters here that return an
enum type, e.g. getOptLevel(), getOutFileType(), getTargetArch(), getVerbose(),
etc.

Done.

I don't think you need "Ice::" here and above since you're already in the Ice
namespace.

Done.
