Nice. While you are looking at those values that don't fit anymore with AVX512,
there is one place I forgot when I patched the neighbors in simplify-rtx.c:3668
if (sel & (1 << UINTVAL (j)))
The 1 is supposed to be HOST_WIDE_INT_1U.
(IIRC we will be in trouble if there is ever an AVX1024 with vectors of chars,
as even hwi will be too small...)
