This test uses 'wire real' but specified the '-gno-xtypes' option.
This is because it named a variable 'wreal' which is a keyword when
that option is enabled.
By adding ivtest to the iverilog source tree, it is easier to keep
the regression test synchronized with the source that is being tested.
This should be especially helpful for PRs that add a new feature, and
have a matching ivtest PR with the regression test for that feature.
