[SPARK-6152] Use shaded ASM5 to support closure cleaning of Java 8 compiled
classes
This patch modifies Spark's closure cleaner (and a few other places) to use
ASM 5, which is necessary in order to support cleaning of closures that were
compiled by Java 8.
In order to avoid ASM dependency conflicts, Spark excludes ASM from all of
its dependencies and uses a shaded version of ASM 4 that comes from
`reflectasm` (see [SPARK-782](https://issues.apache.org/jira/browse/SPARK-782)
and #232). This patch updates Spark to use a shaded version of ASM 5.0.4 that
was published by the Apache XBean project; the POM used to create the shaded
artifact can be found at
https://github.com/apache/geronimo-xbean/blob/xbean-4.4/xbean-asm5-shaded/pom.xml.

was a useful resource while upgrading the code to use the new ASM5 opcodes.
