- Added a libasm option (libasm.output.synth.instrs) to disable synthetic instructions (it makes it easier to translate to IR without them)

- Simplified the sparc backend since we dont have to deal with synthetic instructions anymore

- synthetic instruction support is still here by default, just disable the option if you want to translate to IR and not manually understand the code

- This change fixed translation support for synthetic instructions that were previously badly supported.
