After discuss with paul, it is not a good idea to combine two fix together in
one webrev. I will handle them separately
Please help review the updated one. Thanks!

Dear All,
May I ask your help to review this change:
Webrev: http://cr.openjdk.java.net/~lzang/8252101/webrev.00/
CSR: https://bugs.openjdk.java.net/browse/JDK-8252102
Bug: https://bugs.openjdk.java.net/browse/JDK-8252101
This change adds the description of expected behavior for jmap
-hiso/-dump to use "all" and "live" at the same time.
With Paul's help, It also includes code refine of the dump()
function in Jmap.java. which is based on Paul's change
