  Log Message:
  -----------
  [GISel][AArch64][RISCV] Allow G_SEXT_INREG patterns to be imported. (#115576)

SelectionDAG uses VTSDNode to store the extension type. GlobalISel uses
a literal constant operand.

For vectors, SelectionDAG uses a type with the same number of elements
as other operand of the sext_inreg. I assume for GISel we would just use
the scalar size.
