Hi,

g++.dg/vect/slp-pr50413.cc should check that the basic block in shift
() doesn't get vectorized. This patch removes other functions that
contain basic blocks that can be vectorizable on some platforms.

Tested on x86_64-suse-linux.
Committed to trunk.

Ira

testsuite/ChangeLog:

        * g++.dg/vect/slp-pr50413.cc: Don't run the test.  Remove main ()
        and get_bit ().
