I've made a quick attempt (replacing an existing dg-skip-if with
dg-xfail-if in vcvt_high-1.c)
and I do see XFAIL and UNRESOLVED.
But this seems normal in this case, because:
- when using dg-skip-if, the test was not compiled (skipped)
- when using dg-xfail-if, the test is actually compiled, leading to
compilation errors which are reported as UNRESOLVED

My test was:

cp k.c gcc/testsuite/gcc.target/aarch64
cp k.c gcc/testsuite/gcc.target/aarch64/advsimd-intrinsics/

cat k.c
===
/* { dg-xfail-if "" { aarch64*-*-* } } */
int c (

make check RUNTESTFLAGS="advsimd-intrinsics.exp=k.c"

# of expected failures       8
# of unresolved testcases    8

make check RUNTESTFLAGS="aarch64.exp=k.c"

# of expected failures       1

The iteration number doesn't matter, but there wan't extra unresolved
failures when it's driven by aarch64.exp.
