[AArch64][SVE] Remove index_vector node.

Authored by junparser on Apr 29 2021, 7:32 PM.



Since index_vector is lowered into step_vector in D100816, we can just remove
index_vector, use step_vector for codegen directly.

Please can you also remove INDEX_VECTOR from the AArch64ISD enum.


As a tidy up I'd say these multiclasses are intrinsically linked to stepvector and related nodes. As these nodes now have a unified form I personally don't see much value with the indirection and think they can use all the operations directly within the multiclass.


The add(mul(step_vector comments in this class and sve_int_index_rr are missing a close ) for the mul.
