Tweak some optimizations.
Delegates passed to inlined functions now also stand a chance of being inlined.
This should make opApply as efficient as a regular loop, as long as both opApply
and the foreachbody are eligible for inlining; which is to say most non-virtual
opApply invocations will likely get fully inlined now.
(Note: above requires -O2 -enable-inlining or -O3)
