Future Updates to hcl Tutorials

[smc447]

Tutorial 1
need to add .v to a
code snippet:

def simple_compute(a, A):

    B = hcl.compute(A.shape, lambda x, y: A[x, y] + a, "B")

Tutorial 7:
need to add outline function because nested loop
error message:
raise RuntimeError(
RuntimeError: hcl.return_ statement cannot be in a nested region due to MLIR's limitation. Please rewrite your program and use .outline() to create a new function.

Tutorial 8:
works if you take out the +2 in indexing for computing.
Since this tutorial is about the backend, you can probably take out the +2 .
part of code causing the error:

A = hcl.placeholder((10, 10), "A")
def kernel(A):
    return hcl.compute((8, 8), lambda y, x: A[y][x] + A[y+2][x+2], "B")

Without taking out the +2 in the indexing, the error you get is:

Tutorial 9:
SODA not a supported target, so tutorial unable to run

Thanks Sofia! The above issues have been solved, now the tutorials pass the test and have been added to the CI
