Made Addrcheck distinguish between invalid reads and invalid writes (previously
was just saying "invalid memory access").

Added a regression test for this, for memcheck and addrcheck.  Also made
Addrcheck use Memcheck's fprw regtest.  Was able to remove the not-very-useful
'true' test for Addrcheck now that it has a couple of real tests.
