Hexagon (target/hexagon) generator phase 2 - generate header files

Python scripts generate the following files
    helper_protos_generated.h.inc
        For each instruction we create DEF_HELPER function prototype
    helper_funcs_generated.c.inc
        For each instruction we create the helper function definition
    tcg_funcs_generated.c.inc
        For each instruction we create TCG code to generate call to helper
    tcg_func_table_generated.c.inc
        Table of function pointers indexed by opcode
    shortcode_generated.h.inc
        Generate a table of instruction "shortcode" semantics
    opcodes_def_generated.h.inc
        Gives a list of all the opcodes
    op_attribs_generated.h.inc
        Lists all the attributes associated with each instruction
    op_regs_generated.h.inc
        Lists the register and immediate operands for each instruction
    printinsn_generated.h.inc
        Data for printing (disassembling) each instruction (format
        string + operands)
