Tom Stellard 6778dd6fa7 AMDGPU: Insert two S_NOP instructions for every high level source statement. 
Patch by: Konstantin Zhuravlyov

Summary: Tools, such as debugger, need to pause execution based on user input (i.e. breakpoint). In order to do this, two S_NOP instructions are inserted for each high level source statement: one before first isa instruction of high level source statement, and one after last isa instruction of high level source statement. Further, debugger may replace S_NOP instructions with S_TRAP instructions based on user input.
