Remove the line "For use for simulation and test purposes only" in files
were AMD is the only copyright holder listed in the header. This happens
to be the case for all files where this line exists, removing it
completely from gem5.

Global instructions are new in Vega and are essentially FLAT
instructions from GCN3 but guaranteed to go to global memory where as
flat can go to global or local memory.
This reworks the flat instruction classes so that the initiateAcc /
execute / completeAcc logic can be reused for flat, global, and later
scratch subtypes of flat instructions. The decoder creates a flat
instruction class which sets instruction flags based on the flat
instruction's SEG field. There are new initOperandInfo and
generateDissasmbly methods for flat and global. The number of operands
and operand index getters are modified to check the flags and return the
correct value for the subtype.

this patch removes the GPUStaticInst enums that were defined in GPU.py.
instead, a simple set of attribute flags that can be set in the base
instruction class are used. this will help unify the attributes of HSAIL
and machine ISA instructions within the model itself.
because the static instrution now carries the attributes, a GPUDynInst
must carry a pointer to a valid GPUStaticInst so a new static kernel launch
instruction is added, which carries the attributes needed to perform a
the kernel launch.
