    aarch64: Make C/C++ operations possible on SVE ACLE types.
    
    This patch changes the TYPE_INDIVISBLE flag to 0 to enable SVE ACLE types 
to be
    treated as GNU vectors and have the same semantics with operations that are
    defined on GNU vectors.
    
    gcc/ChangeLog:
    
            * config/aarch64/aarch64-sve-builtins.cc (register_builtin_types): 
Flip
            TYPE_INDIVISBLE flag for SVE ACLE vector types.
