For radeonsi, native and TGSI use different compilers and this results in different limits for different IR's. The set we strictly need for radeonsi is only the MAX_BLOCK_SIZE and MAX_THREADS_PER_BLOCK params, but I added a few others as shader related that seemed like they would also typically depend on the compiler.
