[PATCH] Address lowering [3/3] Test suite additions and changes

["William J. Schmidt" <wschmidt at linux dot vnet dot ibm dot com>]

Here is the third patch related to address lowering.  It contains the
changes to the test suite:  13 new tests, and 18 tests that needed to be
modified.  The latter occur because of specific patterns expected in
tree dumps; for example, a field reference x.f might now be expected to
be a MEM_REF instead.  In a couple of cases, I found it preferable to
disable address lowering for the test.

Thanks,
Bill
