We had been using thread_local index -> opcode_desc tables to avoid plumbing through a storage location throughout all the code. But now we have done so with the new brw_isa_info structure. So we can just store the tables there, and initialize it with the compiler. This fixes crashes in gtk4-demo on iris, and should help with some programs on zink as well. Something was going wrong with the thread_local variables not being set up correctly. While we might be able to work around that issue, there's really no advantage to storing these lookup tables in TLS (beyond it being simpler to do originally). So let's simply stop doing so.
