* ループ回数の設定

* プの実行時間が約0.4秒になるように設定する．この設定のために，
* LOOP_REF回の空ループの実行時間を，その前後でget_timを呼ぶことで
* 測定し，その測定結果から空ループの実行時間が0.4秒になるループ回
* 数を求め，task_loopに設定する．
*
* LOOP_REFは，デフォルトでは1,000,000に設定しているが，想定したよ
* り遅いプロセッサでは，サンプルプログラムの実行開始に時間がかか
* りすぎるという問題を生じる．逆に想定したより速いプロセッサでは，
* LOOP_REF回の空ループの実行時間が短くなり，task_loopに設定する値
* の誤差が大きくなるという問題がある．
*
* そこで，そのようなターゲットでは，target_test.hで，LOOP_REFを適
* 切な値に定義するのが望ましい．
*
* また，task_loopの値を固定したい場合には，その値をTASK_LOOPにマ
* クロ定義する．TASK_LOOPがマクロ定義されている場合，上記の測定を
* 行わずに，TASK_LOOPに定義された値を空ループの回数とする．
*
* ターゲットによっては，空ループの実行時間の1回目の測定で，本来よ
* りも長めになるものがある．このようなターゲットでは，MEASURE_TWICE
* をマクロ定義することで，1回目の測定結果を捨てて，2回目の測定結果
* を使う．
