This is a significantly expanded upon follow up to [1], and
specifically the last 5 patches in that series.
While looking at implementing the improvements suggested by Peter, I
realized that there were many additional areas in which our handling
of defaults was suboptimal, with the relevant code scattered all over
the place and sometimes duplicated. So I set out to rationalize
things.
I ended up changing very little in terms of observable behavior
outside of RISC-V, where I feel that we still have leeway to make
things right before it reaches significant adoption and backwards
compatibility becomes a major concern.
