[PATCH 1/3] testsuite: Add check for vectors of 128 bits being supported

[Maciej W. Rozycki]

Similarly to checks for vectors of 32 bits and 64 bits being supported 
add one for vectors of 128 bits.

        gcc/testsuite/
        * lib/target-supports.exp (check_effective_target_vect128): New 
        procedure.
