GTE Test

This is a GTE test program which will check the behavior of GTE registers and (official) GTE opcodes. The opcodes are verified by comparing the results with a software simulation. Running the full test does take hours on a real PSX, and probably isn't much faster on an emulator either. However, the tests will give up after a certain amount of errors, so when run on an inaccurate emulator, it will completey quickly.
