Partial fix to allow partitions to have boundary temporaries of unknown size.
The old behavior was that we'd fall back to full model CPU execution at
compilation time; the new behavior is that we'll get ordinary
partitioned compilation and execution.
Limitations:
- Needs more testing and more tests written.
- The initial guess for the size of a boundary temporary is a single
element. Perhaps it would be useful to remember actual size from
a previous execution.
- Fenced execution punts to unfenced execution (at the NDK API level)
when plan contains subgraph outputs of unknown size.
- Operands of unknown size at control flow construct boundaries still
falls back to full model CPU execution.
Also adds some diagnostic logging.
