- Move codegen tests to a sub directory
- Add tests for all functions of Expression, ExpressionRef, and ExpressionGraph
- Respect dependencies during tests: The ExpressionGraph test doesn't
use ExpressionRef anymore.
The new tests revealed a few bugs so the following changes were made:
- Expression::MakeNop now resets the current expression with the default
constructed NOP expression
- ExpressionGraph::Insert now updates the lhs_id the same way as
InsertBack()
