    Fix calling convention incompatibility with vendor compiler

    For the 20th anniversary of https://gcc.gnu.org/gcc-3.4/sparc-abi.html,
    a new calling convention incompatibility with the vendor compiler (and
    the ABI) has been discovered in 64-bit mode, affecting small structures
    containing arrays of floating-point components.  The decision has been
    made to fix it on Solaris only at this point.

    gcc/
            PR target/114416
            * config/sparc/sparc.h (SUN_V9_ABI_COMPATIBILITY): New macro.
            * config/sparc/sol2.h (SUN_V9_ABI_COMPATIBILITY): Redefine it.
            * config/sparc/sparc.cc (fp_type_for_abi): New predicate.
            (traverse_record_type): Use it to spot floating-point types.
            (compute_fp_layout): Also deal with array types.
