6bdb838a - [CIR] Upstream vec shuffle builtins in CIR codegen (#169178)

[CIR] Upstream vec shuffle builtins in CIR codegen (#169178) This PR is part of #167752. It upstreams the codegen and tests for the shuffle builtins implemented in the incubator, including: - `vinsert` + `insert` - `pblend` + `blend` - `vpermilp` - `pshuf` + `shufp` - `palignr` It does NOT upstream the `perm`, `vperm2`, `vpshuf`, `shuf_i` / `shuf_f` and `align` builtins, which are not yet implemented in the incubator. This _is_ a large commit, but most of it is tests. The `pshufd` / `vpermilp` builtins seem to have no test coverage in the incubator, what should I do?
