Simon Pilgrim	812e64ef0c	[DAG] MatchRotate - support rotate-by-constant of illegal types ... Patch to fix some of the regressions in D77804. By folding to rotate/funnel-shift by constant amounts for illegal types, we prevent SimplifyDemandedBits from destroying the patterns prematurely, allowing us to use the rotate/funnel-shift legalization that was added in D112443.

Charlie Turner	458e79b814	[ARM] Expand ROTL and ROTR of vector value types ... Summary: After D13851 landed, we saw backend crashes when compiling the reduced test case included in this patch. The right fix seems to be to allow these vector types for expansion in instruction selection.
