Detailed Description
A for loop.
Execute the 'body' statement for all values of the variable 'name' from 'min' to 'min + extent'. There are four types of For nodes. A 'Serial' for loop is a conventional one. In a 'Parallel' for loop, each iteration of the loop happens in parallel or in some unspecified order. In a 'Vectorized' for loop, each iteration maps to one SIMD lane, and the whole loop is executed in one shot. For this case, 'extent' must be some small integer constant (probably 4, 8, or 16). An 'Unrolled' for loop compiles to a completely unrolled version of the loop. Each iteration becomes its own statement. Again in this case, 'extent' should be a small integer constant.
