linking when !HAVE_LD_PIE that isn't already broken if you choose to

    • Implement P0479R5, [[likely]] and [[unlikely]]. · 2674fa47 
      [[likely]] and [[unlikely]] are equivalent to the GNU hot/cold attributes,
except that they can be applied to arbitrary statements as well as labels;
this is most likely to be useful for marking if/else branches as likely or
unlikely.  Conveniently, PREDICT_EXPR fits the bill nicely as a
representation.

I also had to fix marking case labels as hot/cold, which didn't work before.
Which then required me to force __attribute ((fallthrough)) to apply to the
statement rather than the label.

    • When running the testsuite on boards that can't report an error status DejaGNU... · fe5d1296 
      When running the testsuite on boards that can't report an error status
DejaGNU uses a special wrapper to print the exit code on stdout and
parses stdout to find whether an execution failed or passed.

In testcases that use "freopen (..., ..., stdout)" this special line is
printed to the alternate location described in the freopen call and
DejaGNU can't find the error code.

This results in DejaGNU using a default return status of 2 and the test
failing.

This patch skips the two testcases that use freopen on stdout when
testing a board that requires this wrapper.


Testing done by running these two tests on arm-none-eabi cross build and
observing that they are unsupported.
