[X86] Add a few test cases for a v8i64 sext/zext from an illegal type that needs to be promoted to 128 bits.
If v8i64 isn't a legal type but v4i64 is, these will be split and then each half will get their input promoted and become an any_extend_vector_inreg/punpckhwd + any_extend + and/sign_extend_inreg.
If we instead recognize the input will be promoted we can emit the and/sign_extend_inreg first in a 128 bit register. Then we can sign_extend/zero_extend one half and pshufd+sign_extend/zero_extend the other half.
