On JDK-8281518

[Julian Waters]

>From the discussion on JDK-8281518:
"What *would* get us benefit in a cost-effective way would be to take
this optimization and several previous ones (and future ones) and
refactor them into a single comprehensive analysis based on truth
tables, which would normalize bitwise expressions up to some particular
complexity (say, up to three input variables and up to depth 2, with
variety of operators). This is a minor research project, but (I think)
a worthy one."

Out of curiosity, do we have an exhaustive list of related optimizations
prior to this one already included in C2?
