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.
