Throughout an effort to strongly check the behavior of CodeGen with the IR shufflevector instruction we generated many tests while predicting the best X86 sequence that may be generated.
This is a subset of the generated tests that we think may add value to our X86 set of tests.
Some of the checks are not optimal and will be changed after fixing:
#. PR34394
#. PR34382
#. PR34380
#. PR34359
This test doesn't really check any AVX512 support, because it will be folded early in the target-indpenendent dagcombine.
