Changed simd-7 test for C and Fortran to lower the execution time to ~0.6 and ~1 second respectively while keeping the test representative. Measured the time like:
$ time make check-target-libgomp RUNTESTFLAGS="c.exp"=simd-7.c on a Linux x86-64 machine. (Without the patch I also had a very long time: ~7.5 and ~60 seconds) 2015-07-20 22:40 GMT+03:00 H.J.

PR libgomp/66950
* testsuite/libgomp.c/examples-4/simd-7.c: Lower the defined constant
N to 30. Add iterative reference function for Fibonacci numbers
- fib_ref.
(fib): Correct corner cases in the recursion.
(main): Replace the non-simd loop with fib_ref call.
* testsuite/libgomp.fortran/examples-4/simd-7.f90: Add iterative
reference subroutine for Fibonacci numbers - fib_ref.
(fibonacci): Lower the parameter N to 30. Correct accordingly check for
the last array element value. Replace the non-simd loop with fib_ref
call. Remove redundant b_ref array. Remove the comparison of the last
array element with according Fibbonacci sequence element.
(fib): Correct corner cases in the recursion.
