  Log Message:
  -----------
  [mlir][Linalg] Allow specifiying zero-rank shaped type operands to linalg.generic ops.

Fixing a bug where using a zero-rank shaped type operand to
linalg.generic ops hit an unrelated assert. This also meant that
lowering the operation to loops was not supported. Adding roundtrip
tests and lowering to loops test for zero-rank shaped type operand
with fixes to make the test pass.
