radeonsi: write shader asm annotated with wave info into GPU hang reports

radeonsi: write shader asm annotated with wave info into GPU hang reports

Note that the disassembly is written twice - first the unmodified compiler
output and then the wave-annotated output only if there are waves executing
the shader.

Sample output from a real GPU hang most likely caused by image_sample:

The number of active waves = 28
