Silviu Baranga 82abdf7e36 [DAGCombine] Truncate BUILD_VECTOR operators if necessary when constant folding vectors 
Summary:
The BUILD_VECTOR node will truncate its operators to match the
type. We need to take this into account when constant folding -
we need to perform a truncation before constant folding the elements.
This is because the upper bits can change the result, depending on
the operation type (for example this is the case for min/max).

This change also adds a regression test.
