8038498: Fix includes and C inlining after 8035330
Summary: 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.

342 | 33 // A BufferingOops closure tries to separate out the cost of finding roots |
34 // from the cost of applying closures to them. It maintains an array of | |
35 // ref-containing locations. Until the array is full, applying the closure | |
36 // to an oop* merely records that location in the array. Since this | |
37 // closure app cost is small, an elapsed timer can approximately attribute | |
38 // all of this cost to the cost of finding the roots. When the array fills | |
39 // up, the wrapped closure is applied to all elements, keeping track of | |
40 // this elapsed time of this process, and leaving the array empty. | |
41 // The caller must be sure to call "done" to process any unprocessed | |
42 // buffered entriess. | |
