    arm,testsuite: Fix vect-half-floats.c test
    
    This patch fixes typos in effective targets which otherwise lead to
    DejaGnu errors.
    
    It also replaces dg-additional-options with dg-options to avoid
    compiling with -ansi -pedantic-errors, resulting in
    error: ISO C does not support the '_Float16' type [-Wpedantic]
