Hi,
by packing the coder and length values into a long, and combining the
length and coder mixers, we can reduce the number of MHs generated to
set up String concatenations.
Theoretically we reduce the number of MHs created by up to a third,
and real time improvements in startup tests exercising ISC typically
hover around 10%. This optimization reverts JDK-8212597[1], so
expressions that benefited from that of course sees a smaller or no
added benefit.

This looks okay to me.
