8012335: G1: Fix bug with compressed oops in template interpreter on x86 and sparc. Summary: In do_oop_store the uncompressed value of the oop being stored needs to be preserved and passed to g1_write_barrier_post. This is necessary for the heap region cross check to work correctly. Reviewed-by: coleenp, johnc Contributed-by: Martin Doerr <martin.doerr@sap.com>
