RFR: [8u20]: 8037221: [asm] refresh internal ASM version

[Kumar Srinivasan]

Hello,

Please review and approve the back-port of the above fix, the fix is 
simply a refresh of the
sources from ObjectWeb's ASM5_GA.

The bug:
https://bugs.openjdk.java.net/browse/JDK-8037221
Webrev in for jdk9:
http://cr.openjdk.java.net/~ksrini/8037221/webrev.0/
Changeset for jdk9:
http://hg.openjdk.java.net/jdk9/dev/jdk/rev/a791773d6e91

The backport:
https://bugs.openjdk.java.net/browse/JDK-8037478

Webrev for jdk8u20:
http://cr.openjdk.java.net/~ksrini/8037221/webrev.1/

There is a subtle difference between the two, for 8u20  the following
two files  were removed, since those changes don't exist in 8 and 8u20.

src/share/classes/jdk/internal/org/objectweb/asm/tree/MethodNode.java
src/share/classes/jdk/internal/org/objectweb/asm/tree/analysis/AnalyzerException.java


Thanks in advance.
Kumar
