[RISCV] Replace AddiPair ComplexPattern with a PatLeaf. NFC

The ComplexPattern is looking for an immediate in a certain range
that has a single use. This can be handled with a PatLeaf since
we aren't matching multiple patterns or checking any complicated
relationships between nodes.

This shrinks the isel table a little bit since tablegen no longer
has to generate patterns with commuted operands. With the PatLeaf,
tablegen can see we're matching an immediate which should always
be on the right hand side of add.
