[PATCH]middle-end: Fix two testisms on x86 after PFA [PR118754]

[Tamar Christina]

Hi All,

These two tests now vectorize the result finding
loop with PFA and so the number of loops checked
fails.

This fixes them by adding #pragma GCC novector to
the testcases.

Regtested on x86_64-pc-linux-gnu on an AVX512 machine
with -m32, -m64 and test pass again.

Ok for master?

Thanks,
Tamar
