Roland Froese 732fe22454 [PowerPC] Avoid scalarization of vector truncate
The PowerPC code generator currently scalarizes vector truncates that would fit in a vector register, resulting in vector extracts, scalar operations, and vector merges. This patch custom lowers a vector truncate that would fit in a register to a vector shuffle instead.
