Uday Bondhugula d18ae9e2c7 Constant folding for loop bounds. ... - Fold the lower/upper bound of a loop to a constant whenever the result of the application of the bound's affine map on the operand list yields a constant. - Update/complete 'for' stmt's API to set lower/upper bounds with operands. Resolve TODOs for ForStmt::set{Lower,Upper}Bound. - Moved AffineExprConstantFolder into AffineMap.cpp and added AffineMap::constantFold to be used by both AffineApplyOp and ForStmt::constantFoldBound.
