OK so here is a conclusion for another follow-up PR to deal with constant
lifting.
- Pattern input `ConstantPattern`:
- Only match constant nodes and keep them in the partitioned functions.
In this case, the arguments of partitioned functions will be reduced.
- Pattern input `VarPattern('x')`:
- Match only the var node with a specified name hint. In this case, the
arguments of partitioned function is fixed.
- Pattern input `wildcard` or `VarPattern('x') | ConstantPattern`:
- Match both constant and var node but life constant nodes. In this
case, the arguments of partitioned function is fixed whever it matches constant
or var.
