Several source files privately defined macros LIKELY and UNLIKELY in terms of __builtin_expect. But <cutils/compiler.h> already has CC_LIKELY and CC_UNLIKELY which are intended for this purpose. So rename the private uses to use the standard names. In addition, AudioFlinger was relying on the macro expanding to extra ( ). Change-Id: I2494e087a0c0cac0ac998335f5e9c8ad02955873
