RFR (XXS): 8145673: G1RemSetSummary.hpp uses FREE_C_HEAP_ARRAY

[Thomas Schatzl]

Hi all,

  can I have reviews for this change that fixes some include problem
with G1RemSetSummary?

The .hpp file uses FREE_C_HEAP_ARRAY, which is defined in an .inline.hpp
file. For some reason, g1RemSetSummary.hpp does not even include that
one, but only relies on other code using it doing the right thing (tm).

The fix is to move the code into the .cpp file and do the correct
includes.
