Remove inline qualifier of isl_sioimath_gcd
isl_sioimath_gcd is referenced only outside of isl_int_sioimath.c, i.e.
the inline qualifier does not make sense. It still has external linkage
because of a forward declaration without inline qualifier in
isl_int_sioimath.h.
Visual Studio however ignores the forward declaration and therefore
does not generate a isl_sioimath_gcd symbol which results in a link
error.
This is fixed by removing the inline qualifier, declaring it
unambiguously with external linkage.
