I think this should be prohibited at all costs. This is a very slow operation
on every architecture other than x64.

I'm carefully crafting std.simd with functions that encourage the best results
on all platforms, and I'm addressing this issue there.

Allowing this implicit case would ruin many libraries implementing SIMD code on
all non-x64 platforms. They should rather be encouraged to use the library
appropriately instead.
