Michael Kuperstein fd350586f5 [DAGCombine] Slightly improve lowering of BUILD_VECTOR into a shuffle. ... This handles the case of a BUILD_VECTOR being constructed out of elements extracted from a vector twice the size of the result vector. Previously this was always scalarized. Now, we try to construct a shuffle node that feeds on extract_subvectors. This fixes PR15872 and provides a partial fix for PR21711.
