Dinar Temirbulatov 7f05bdf4ee [AArch64][SME] Fix an infinite loop in DAGCombine related to adding -force-streaming-compatible-sve flag.
Compiler hits infinite loop in DAGCombine. For force-streaming-compatible-sve
mode we have custom lowering for 128-bit vector splats and later in
DAGCombiner::SimplifyVCastOp() we scalarized SPLAT because we have custom
lowering for SME. Later, we restored SPLAT opertion via performMulCombine().
