Andrea Di Biagio 96db9b8ed8 [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.
