Similar to how we treat catch entry instructions, this cl adds new
function and osr entry instructions. The [FunctionEntry] and
[OsrEntry] - just like [CatchBlockEntry] - have now their own initial
definitions. The [GraphEntry] has only initial definitions for
constants.
Explicit phis are inserted for all parameter / special parameter
instructions if necessary.
Future work is:
a) Minimize parallel moves due to the phis on parameters
b) Cleanup frame setup: Move it entirely into FunctionEntry/CatchEntry
(instead of the split version we have now)
