[PATCH 0/3] fix discarded label statement

[Luc Van Oostenryck <luc.vanoostenryck@gmail.com>]

This series fixes a bug occurring when code contains an unsed statement.
In this case, not only the label is ignored, but the following statement
is also erroneously discarded together with the label.

This can be easily verified by inspecting the output of test-linearize
but can't be tested directly with the current test suite.
So patches 1 & 2 contain two small improvements to the test suite that
allow to test this sort of thing directly, the fix itself and its test
are in patch 3.

Luc Van Oostenryck (3):
  testsuite: add tag to ignore the output/error
  testsuite: check patterns presence or absence in output
  fix discarded label statement
