radv: add initial trap handler support with RADV_TRAP_HANDLER=1

Browse Source 
A trap handler is used to handle shader exceptions like memory
violations, divide by zero etc. The trap handler shader code will
help to identify the faulty shader/instruction and to report
more information for better debugging.

This has only been tested on GFX8, though it should work on GFX6-GFX7.
It seems we need a different implemenation for GFX9+.
