Set Processes comm name to package name

When debugging audit logs, it is often helpful to
have the packages name. Bear in mind that the
package name is the right most chars up to
TASK_COMM_LEN. Although a possibility of truncation
exists, it can be useful for narrowing down the
possibilities.

ISH (Inner Shareable) should be sufficient for all cores/clusters,
but is not sufficient for GPU or other memory-mapped peripherals

This should improve performance in certain cases without harming
correctness.

jars added causes the dalvik to crash while performing dexopt

which is part of libcore.java.util.jar.DalvikExecTest class.

dalvik: use T3 branch when target offset is too large

T1 branch has offset limit of [-256, 254]. T3 branch has offset
limit of [-1048576, 1048574]. Use T3 branch when target offset
falls outside T1 range to avoid compiliation abort.
