ASM Priority Boost Tool
This tool is a replacement for the Jack plugin that allows injection
of static method calls before lock enter and exit.
A common use case would be to boost a thread's priority as soon as
it acquires a heavily contented lock and resetting the priority upon
release.
This tool is meant to be optionally invoked from /build/core/ rules
during the build process.
Test: JUnit Tests / resulting image on a bullhead.
