7173494: some jdk tests are not run in test/Makefile

[Alan Bateman]

This one is a small clean-up of the test targets defined in 
jdk/test/Makefile. The union of the tests executed by each of the make 
targets should be the entire test suite but this isn't so, there are 
small number of tests that aren't run.

I've renamed jdk_misc to jdk_other (the original name is confusing 
because of sun.misc) and expanded it to run additional areas that have a 
small number of tests. If more tests are added to these areas over time 
then it may make sense to add new targets in the future.

"make jdk_jmx" now runs the JMX tests as it was confusing to have those 
tests split between management1 and management2. I've also renamed 
jdk_tools1 to jdk_jdi to make it clear that this is the JDI tests rather 
than tools. When Kelly originally set this up he split the NIO tests 
into 3 batches, I don't think this is necessary any longer (the really 
slow tests have been long been dialed down or changed to run much faster).
