[PATCH 6/6] test: Check declaration (without init) inside a probe

[eugene.loh@oracle.com]

From: Eugene Loh <eugene.loh@oracle.com>

We test that declaration (with init) of a variable inside a probe is not
allowed.

Check also that declaration without init inside a probe is also
forbidden.

The related test/unittest/probes/err.D_SYNTAX/err.D_SYNTAX.declare*.d
tests are left alone.
