    aarch64: PR target/99195 annotate more simple binary ops for vec-concat with zero
    
    More pattern annotations and tests to eliminate redundant vec-concat with zero instructions.
    These are for the abd family of instructions and the pairwise floating-point max/min and fadd
    operations too.
    
    Bootstrapped and tested on aarch64-none-linux-gnu.
