  |     [PATCH] i386: Enable 512-bit byte dot-product only under AVX512BW [PR126098]
  |     
  |     The byte sdot_prod/udot_prod expanders used the VI1_AVX512VNNIBW
  |     iterator, which enabled V64QI under AVX512BW || AVX512VNNI.  But VNNI
  |     has no same-sign byte instruction (VPDPBUSD is mixed-sign, i.e. usdot),
  | ... 28 lines of the commit log omitted.
  | ... applied on top of baseline commit:
  | 9c36ceaacc0 i386.cc: Add a missing override specifier
