Nadav Rotem 7e413e9c94 The type-legalizer often scalarizes code. One of the common patterns is extract-and-truncate.

In this patch we optimize this pattern and convert the sequence into extract op of a narrow type.
This allows the BUILD_VECTOR dag optimizations to construct efficient shuffle operations in many cases.
