[X86] EltsFromConsecutiveLoads - only attempt to recognise reverse patterns from all load element patterns (#170852) Noticed while investigating a regression reported after #168706 - don't attempt this if any elements are zero/undef - there is a potential issue with reverse(insert_subvector(undef,load(),0)) patterns - but I haven't managed to create a fail case.
