This series adds support for two SpacemiT vendor extensions implementing
subsets of the SpacemiT Intrinsic Matrix Extension (IME) specification:

  - XsmtVdot v1.0: Vector Dot Product Extension, implemented by SpacemiT X60
  - XsmtVdotII v1.0: Vector Dot Product II Extension, implemented by
    SpacemiT A100

Changes since v5:
  - Fix grammar: "implement" -> "implements".
  - riscv-dis.c: Jump to undefined_modifier when 'wi' field is neither 2 nor 3.
  - riscv-opc.c: Remove the misleading comment.
