radeonsi: implement TGSI opcodes TEX_LZ and TXF_LZ
This massively decreases VGPR spilling for DiRT Showdown, because we
no longer have to use v4i32 for 2D fetches when level == 0.
We now use v2i32 for those cases.
DiRT Showdown - Spilled VGPRs: -26 (-81%)
This surprisingly doesn't have any useful effect on performance (+ 0.05%).
