emma library is used for collecting code coverage. Current pain point is that
for collecting code coverage, developers either need to include emma as a
local static library, or change BOOTCLASSPATH to include emma which includes
hacking boot image and reflashing it.

With this change, emma will be integrated into core.jar if EMMA_INSTRUMENT flag
is on, so pushing the updated framework.jar and perform a runtime restart will
make emma globally available to all code coverage tests.

This change will only affect code coverage builds.
