[9/11][POC][Clang][RISCV] Define tuple type variant of vsoxseg2ei32 vsuxseg2ei32

[eopXD]

Summary

For the cover letter of this patch-set, please checkout D146872.

Depends on D147914.

This is the 9th patch of the patch-set.

This patch is a proof-of-concept and will be extended to full coverage
in the future. Currently, the old non-tuple indexed segment store is
not removed, and only signed integer indexed segment store of NF=2,
EEW=32 is defined here.

Address comment from Craig.

[eopXD]

Rebase.

[eopXD]

Reduce variables declared but only used once.

[eopXD]

Removed another variable that is too verbose.

LGTM
