We can use *Set::insert_range to collapse:
for (auto Elem : Range)
Set.insert(E);
down to:
Set.insert_range(Range);
In some cases, we can further fold that into the set declaration.
`let constructor` is legacy (do not use in tree!) since the table gen
backend emits most of the glue logic to build a pass. This PR retires
the td method for Shape and MLProgram
Added pass optimizes MLProgram global operations by reducing to only
the minimal load/store operations for global tensors. This avoids
unnecessary global operations throughout a program and potentially
improves operation gusion.
