liblog: add __attribute__((uninitialized)) to liblog buffers These buffers are immediately written into with *printf() and are in the hot path, so do not initialize them. This saves ~70ns off of each log message, which is ~14% of the overhead within __android_log_print() when writing to a no-op logger. Test: liblog benchmarks Change-Id: I2b898e72c75b57bc63fee565b49a4e00e377ed1a
