Here is an updated version, which already creates the temporary variables f= or each of the partitions, so next step will be start implementing the operati= ons. One thing to figure out I have are loads from memory into large/huge _BitIn= t.=20 I think we could in that case avoid copying into a temporary VAR_DECL if we can pro= ve that in all the use stmts of them the memory they are loading from couldn't= be clobbered (and for the case of a loop merging multiple operations together = the last statement from those), but those statements might very well not have v= ops, so unsure how to find out the current vop SSA_NAME so that I can ask alias oracle.=
