History
Andrea Di Biagio 8cc9059ce8 [InstCombine][X86] Teach how to fold calls to SSE2/AVX2 packed logical shift 
right intrinsics.

A packed logical shift right with a shift count bigger than or equal to the
element size always produces a zero vector. In all other cases, it can be
safely replaced by a 'lshr' instruction.
