That one continues to be hard. ARM processors that support SVE also have
NEON

Hello Ben,
An array type that refers to a vector or matrix type, shall be
denoted with DW_AT_tensor whose integer constant, will specify the
kind of tensor it is. The default type of tensor shall be the kind
used by the vector registers in the target architecture.

Really -- that is what I care about

Here is V3 of what was my vector types proposal.
Changes since V2:
We discussed this extensively in the DWARF for GPUs meeting. Cary
originally wanted it to be a TAG rather than an attribute on an array
and quite frankly, I don't care and so my default position is "What Cary
wants, Cary
