Subject: [AVX512] Pull everything alignr-related into the multiclass
X-Git-Url: http://plrg.eecs.uci.edu/git/?p=oota-llvm.git;a=commitdiff_plain;h=c2b5d999955dcf2d9ea1e4f8561260469fc9eb12

[AVX512] Pull everything alignr-related into the multiclass

The packed integer pattern becomes the DAG pattern for rri and the packed
float, another Pat<> inside the multiclass.

No functional change.
