[RISCV] Expand scalable-vector truncstores and extloads

[frasercrmck]

Summary

Caught in internal testing, these operations are assumed legal by
default, even for scalable vector types. Expand them back into separate
truncations and stores, or loads and extensions.

Also add explicit fixed-length vector tests for these operations, even
though they should have been correct already.

[frasercrmck]

• rebase to hopefully fix the buildbots

You might be better off using integer_scalable_vector_valuetypes(). We need to block mask vectors too.

556

LoadExt for integer fixed vectors is missing.

559

Is the explicit makeArrayRef needed?

[frasercrmck]

• expand operations also for bool and fixed-length types
• remove makearrayref

Good catch, thanks.

Done.

Turns out it's not, thanks.
