[DAGCombiner] Hoist funnel shifts from logic operation

Hoist funnel shift from logic op:
logic_op (FSH x0, x1, s), (FSH y0, y1, s) --> FSH (logic_op x0, y0), (logic_op x1, y1), s

The transformation improves code generated for some cases related to
issue https://github.com/llvm/llvm-project/issues/49541.

Reduced amount of funnel shifts can also improve throughput on x86 CPUs by utilizing more
available ports: https://quick-bench.com/q/gC7AKkJJsDZzRrs_JWDzm9t_iDM
