Nadav Rotem 91e43fd17a When promoting integer vectors we often create ext-loads. This patch adds a ...

dag-combine optimization to implement the ext-load efficiently (using shuffles).

For example the type <4 x i8> is stored in memory as i32, but it needs to
find its way into a <4 x i32> register. Previously we scalarized the memory
access, now we use shuffles.
