69c3c31317 8040002: Clean up code and code duplication in re-diryting cards for verification 
Card re-dirtying code for verification and actual redirtying uses two different, almost completely identical card closures. Also the verification code still assumes a perm gen.

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.
