freedreno/ir3: standalone compiler updates for ir3test

In order to test compiler changes more easily, spit out the assembled
shader with some header information so that we can know about
inputs/outputs more easily.

See: git://people.freedesktop.org/~robclark/ir3test

In ir3test we have a big collection of tgsi shaders and reference
ir3_compiler outputs.  When making compiler changes, regenerate the
compiler outputs and feed to ir3test to compare the new vs reference
shader.
