intel-gpu-tools/debugging: shader debugger

Browse Source 
high level summary of the files:
  * debug_rdata - get current state from debug registers. Helpful
    when developing the debugger, and could serve some purpose in the
    future.
  * eudb - the debugger itself
  * eviction_macro - generate the proper macro to flush the EU render
    cache until I get control flow working
  * pre_cpp - an evaluating c preprocesser like thing, to be used before
    cpp
  * sr - the system routine, exception handler which runs on the EU
  * test - a very basic test system routine
  * debug.h
