testsuite: Fix gen-vect-34.c with vect_masked_load [PR106806]

This is to fix the failure on powerpc as reported in PR106806,
the test case requires tree ifcvt pass to perform on that loop,
and it relies on masked_load support.  The fix is to guard the
expected scan with vect_masked_load effective target.

As tested on powerpc64{,le}-linux-gnu and aarch64-linux-gnu
(cfarm machine), the failures were gone.  But on
x86_64-redhat-linux (cfarm machine) the result becomes from
PASS to N/A.  I think it's expected since that machine doesn't
support AVX by default so both check_avx_available and
vect_masked_load fail, it should work fine on machines with
default AVX support, or if we adjust the current
check_avx_available with current_compiler_flags.
