avx512f-kandnw-1.c and funcspec-5.c seem to be non-PIC related issues. I asked
Kirill to look at them.
Others are not stability but more performance issues - generated code is less
effective than it should be - in one case for some reasons compiler uses
callee-saved ebx in PIC mode instead of edx in non-PIC mode and in xmm case
compiler uses stack in PIC mode instead of xmm register in non-PIC mode
I see that differencies between PIC and non-PIC modes start on reload pass so
I'd like Vlad to look at these cases
