    rs6000: Add dense math register names in darwin.h

    Darwin maintains a separate array of register_names where the Dense Math
    Registers were not added. This caused an ICE when building the darwin
    cross compiler as reported in PR126438. This patch adds dense math
    registers to the REGISTER_NAMES array to fix this issue.
