The default MTYPE initialization in the emulated GPU driver is currently
doing a bitwise AND on an input integer param with other integers
instead of using a bitmask. Change this to use bitset and test the bit
positions corresponding to the values in the MTYPE enum that were
previously being used as an operand for bitwise AND.
This was causing invalid slicc transitions in some benchmarks for
combinations of request type and mtype that are undefined.
