Hi Yumin,

bug: https://bugs.openjdk.java.net/browse/JDK-8135284 webrev: http://cr.openjdk.java.net/~minqi/8135284/webrev00/ Summary: After JDK-8135085 integration, Method increased 4 bytes for 32-bit platforms(no effect for 64 bit). This change removed methodsize from Method which saved 2 bytes for Method. Deleted methodsize related code in SA. The Method size is a constant in Method Type, if it is native method then TWO words added which is consistent with hotspot code. btyecodeOffset in Method.java is no longer useful, the offset is now in ConstMethod so removed too. Tests: JPRT, Runtime Quick test list, run SA on sun.jvm.hotspot.tools.ClassLoaderStats (instrumented Method output to get size). Thanks Yumin
