e00a1f63f8 8039498: Add iterators to GrowableArray 
To simplify the management of multiple code heaps in the code cache (see JDK-8015774), STL-style iterator capability is added to the GrowableArray. Further, custom iterators allow to only iterate over elements that satisfy a given predicate.

f67a3b7e04 8038498: Fix includes and C inlining after 8035330 
Change 8035330: Remove G1ParScanPartialArrayClosure and G1ParScanHeapEvacClosure broke the debug build on AIX. The method do_oop_partial_array() is added in a header, but requires the inline function par_write_ref() through several inlined calls. In some cpp files, like arguments.cpp, par_write_ref() is not defined as the corresponding inline header and is not included. The AIX debug VM does not start because of the missing symbol. This change solves this by cleaning up include dependencies.
