Subject: [PATCH] [X86][SLM] Fix vector PSHUFB + variable shift
 resource/throughputs

Match whats documented in the Intel AOM (+Agner) - PSHUFB xmm is really slow, and mmx/xmm vector shifts are half rate.

Noticed while working to get the cost tables to more closely match llvm-mca analysis, in this case for shifts and truncations.
