RFR - Changes to address CCC 8014135: Support for statically linked agents

[Jeremy Manson]

I know that this is mentioned in the JEP, but does it really make sense to
have -agentpath work here, rather than just -agentlib?  I would think that
specifying a full pathname and getting the library loaded out of the
launcher would be a little surprising to people who are basically saying
"please load this agent from the given path".

Also, in practice, we do something very similar at Google, and, when
testing, I find it occasionally useful to be able to say "please load this
agent on the command line via the agentpath I gave you, rather than loading
the one with the same name I baked into the launcher".

(FWIW, when we did this internally at Google, we added a special -XX flag
for when the agent is in the launcher.  I know that you don't want to go
that way, though.)
