Add partition scheduling primitive. Partition splits a loop into two
sequential loops based on a factor. For example:
```
for i in range(10):
x[i] = 0
```
could be partitioned with a factor of 8 to
```
for i in range(8):
x[i] = 0
for i_ in range(2):
i = i_ + 8
x[i] = 0
```
A couple of changes are necessary to support this change. Feature extraction
had to be updated to handle loops with zero or negative extent and the parallel
vectorize unroll postproc had to be updated to support nested blocks.
