Back when we had a stupid register allocator we did a lot of tricks to optimize the register usage. The old version of rc_find_free_temporary did a full program search each time it was called to find out what registers and channels are actually used and than used that info to give us the first free register to use. Now that we have a proper register allocator both for vertex and fragment shaders, this is no longer needed. Just scan the program when called for the first time to find the first unused temporary index and than increment by one everytime. Regalloc can sort it out later. No change in shader-db confirms this assumption is sound.
