gallium: distinguish between shader IR in get_compute_param

Browse Source 
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.
