Arm64/Sve: Some misc items about SVE Vector Length

kunalspathak commented 5 months ago

List of various items related to vector length and Vector<T> handling in general for SVE:

[ ] Enable Vector256 for SVE, when applicable. Details: https://github.com/dotnet/runtime/pull/101295/files#r1572607279
[ ] See if we can enable the block copy, etc. using Vector256
[ ] Fix getVectorTByteLength() to give correct current vector length instead of hard-coded to return 128.
[ ] Make Vector<T> methods map to Sve intrinsics, whenever possible. So Vector<T> a+b should map to Sve.Add(a,b), etc.
[x] Reuse DOTNET_MaxVectorTBitWidth for Sve. WIP: https://github.com/dotnet/runtime/pull/101295/

@kunalspathak Is this list of items still in scope for 9.0.0, or should we move this into the 10.0.0 milestone?
