Uday Bondhugula ab4797229c Extend loop unroll/unroll-and-jam to affine bounds + refactor related code. ... - extend loop unroll-jam similar to loop unroll for affine bounds - extend both loop unroll/unroll-jam to deal with cleanup loop for non multiple of unroll factor. - extend promotion of single iteration loops to work with affine bounds - fix typo bugs in loop unroll - refactor common code b/w loop unroll and loop unroll-jam - move prototypes of non-pass transforms to LoopUtils.h - add additional builder methods. - introduce loopUnrollUpTo(factor) to unroll by either factor or trip count, whichever is less. - remove Statement::isInnermost (not used for now - will come back at the right place/in right form later) PiperOrigin-RevId: 213471227		2019-03-29 13:15:06 -07:00
