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.

| 58 // user's stack (yes, really!) so the ">>20" handles T1 where the JVM's | |

| 60 // globs of thread blocks contiguously. The "9" has to do with the | |
| 61 // expected size of the T2 thread structure. If these constants are wrong | |
| 62 // the worst thing that'll happen is that the hit rate for heavily threaded | |
| 63 // apps won't be as good as it could be. If you want to burn another | |
| 64 // shift+xor you could mix together _all of the %g7 bits to form the hash, | |
