RFR: JDK-8221543: Indify-dependent microbenchmarks are broken

[Erik Joelsson]

This patch adds running of the Indify tool on the microbenchmark classes 
after building them. The Indify tool is already present in the repo in 
the java/lang/invoke test sources, so I'm building it from there.

Claes, could you take this for spin and see that it works as expected?
