NV50_PROG_DEBUG=1 (assuming you've built mesa with --enable-debug) should dump
the TGSI, nv50 ir (post optimizations and, separately, post-RA), and the actual
instruction stream.

NV50_PROG_OPTIMIZE=0 will disable all of the nv50 ir optimizations, =1 will
enable some of them, =2 will enable most of them (and =3 should be everything).
