glsl: stop cloning builtin fuctions _mesa_glsl_find_builtin_function()
The cloning was introduced in f81ede469910d to fix a problem with shaders including IR that was owned by builtins. However the approach of cloning the whole function each time we reference a builtin lead to a significant reduction in the GLSL IR compilers performance. The previous patch fixes the ownership problem in a more precise way. So we can now remove this cloning. Testing on a Ryzen 7 1800X shows a ~15% decreases in compiling the Deus Ex: Mankind Divided shaders on radeonsi (which take 5min+ on some machines). Looking just at the GLSL IR compiler the speed up is ~40%.
