a6e815c9bd [X86][Atom] Fix vector integer multiplication resource/throughputs 
Match whats documented in the Intel AOM (and Agner/instlatx64 agree) - vector integer multiplies are pipelined - all Port0, throughput = 2 @ 128bits, 1 @ 64bits.

Noticed while checking reduction costs - now that we can use in-order models in llvm-mca, the atom model is the "worst case scenario" we have in x86.

7a6506cfad [NFC][X86][MCA] Add sudo-zero-idiom vperm2f128/vperm2i128 tests - don't break deps 
While btver2 model states that this pattern is a zero-cycle zero-idiom
on Jaguar, it does not appear to be the case on Znver3,
here it measures as not being recognized as dep-breaking zero-idiom,
let alone a zero-cycle one.
