[X86][SSE] combineTruncateWithSat - use truncateVectorWithPACK to chain PACKSS vXi32-vXi8 saturated truncation We can use PACKSS to saturate each stage of the chain: PACKSSDW down to [-32768,32767] and then PACKSSWB to [-128,127]. PACKUS is a little trickier and will be handled in a separate patch. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@325235 91177308-0d34-0410-b5e6-96231b3b80d8
