    aarch64: Fix SVE ACLE regressions from label/symbol_ref patch
    
    7e31e09b7dcb31114114b5719c9f198c013da0e4 regressed several
    SVE ACLE tests because the vec_flags in the newly split-out
    aarch64_valid_ldr_str_offset_p failed to copy the clearing
    of the VEC_PARTIAL flag, which defeated the two later == tests.
