        * config/mips/mips.c (override_options): Set MASK_BRANCHLIKELY
        in target_flags based on ISA, if it was not set on the command
        line.  Warn if MASK_BRANCHLIKLEY is set but the ISA does not
        support Branch Likely instructions.
        * config/mips/mips.h (MASK_BRANCHLIKLEY): New macro.
        (TARGET_BRANCHLIKELY): Likewise.
        (TARGET_SWITCHES): Add -mbranch-likely and -mno-branch-likely.
        (GENERATE_BRANCHLIKELY): Use TARGET_BRANCHLIKELY rather than
        ISA_HAS_BRANCHLIKELY.
        (ISA_HAS_BRANCHLIKELY): Do not include MIPS16 check.
        * doc/invoke.texi: Document new MIPS -mbranch-likely and
        -mno-branch-likely options.
