testsuite: i386: Fix expected vectoriziation in pr105493.c
As reported in PR117079, commit ab18785840d7b8 broke the test pr105493.c.
The test code contains two loops, where the first one is exected to be
vectorized. The commit that broke that vectorization was the first of
several that enabled vectorization of both loops.
Now, that GCC can vectorize the whole function, let's adjust this test
to expect vectorization of both loops by ensuring that we don't write
to the helper-array 'tmp'.
