Fixed 6892265: System.arraycopy unable to reference elements beyond Integer.MAX_VALUE bytes

Problem: Runtime method typeArrayKlass::copy_array() uses int type for pointers calculation.

Solution: Use size_t type in typeArrayKlass::copy_array(). I verified that compiled by C2 code which uses arraycopy stubs works fine. I did not add a regression test since it needs 4Gb java heap and not all our test machines have such memory.

Fix verified (y/n): y, bug's test

Other testing: JPRT
