Fraser Cormack b2ba90aa15 [RISCV] Begin to support more subvector inserts/extracts
This patch adds support for INSERT_SUBVECTOR and EXTRACT_SUBVECTOR
(nominally where both operands are scalable vector types) where the
vector, subvector, and index align sufficiently to allow decomposition
to subregister manipulation:

* For extracts, the extracted subvector must correctly align with the
lower elements of a vector register.
* For inserts, the inserted subvector must be at least one full vector
register, and correctly align as above.

This approach should work for fixed-length vector insertion/extraction
too, but that will come later.
