gallivm: Compile flag to debug TGSI execution through printfs.
It is similar to tgsi_exec.c's DEBUG_EXECUTION compile flag.
I had prototyped this for a while while debugging an issue, but finally
cleaned this up and added a few more bells and whistles.
v2: Use '$' as marker; better output. Thanks to Brian, Zack and Roland
reviews.
Here is a sample output.
