Hi,

this change breaks OpenCL using mesa (clover) with some library functonis implemneted using builtins:

  __attribute__((always_inline)) __attribute__((overloadable)) float copysign(float a, float b) {
      return __builtin_copysignf(a, b)
  }

results in kernel build failure:

  <unknown>:0:0: in function test_1_copysign_float void (float addrspace(1)*, float addrspace(1)*, float addrspace(1)*): unsupported call to function copysignf

Both for R600 (evergreen) and GCN (kaveri)
