    opcodes/arm: add disassembler styling for arm
    
    This commit adds disassembler styling for the ARM architecture.
    
    The ARM disassembler is driven by several instruction tables,
    e.g. cde_opcodes, coprocessor_opcodes, neon_opcodes, etc
    
    The type for elements in each table can vary, but they all have one
    thing in common, a 'const char *  assembler' field.  This field
    contains a string that describes the assembler syntax of the
    instruction.
    
    Embedded within that assembler syntax are various escape characters,
    prefixed with a '%'.  Here's an example of a very simple instruction
    from the arm_opcodes table:
    
      "pld\t%a"
    
    The '%a' indicates a particular type of operand, the function
    print_insn_arm processes the arm_opcodes table, and includes a switch
    statement that handles the '%a' operand, and takes care of printing
    the correct value for that instruction operand.
    
    It is worth noting that there are many print_* functions, each
    function handles a single *_opcodes table, and includes its own switch
    statement for operand handling.  As a result, every *_opcodes table
    uses a different mapping for the operand escape sequences.  This means
    that '%a' might print an address for one *_opcodes table, but in a
    different *_opcodes table '%a' might print a register operand.
    
    Notice as well that in our example above, the instruction mnemonic
    'pld' is embedded within the assembler string.  Some instructions also
    include comments within the assembler string, for example, also from
    the arm_opcodes table:
    
      "nop\t\t\t@ (mov r0, r0)"
    
    here, everything after the '@' is a comment that is displayed at the
    end of the instruction disassembly.
    
    The next complexity is that the meaning of some escape sequences is
    not necessarily fixed.  Consider these two examples from arm_opcodes:
    
      "ldrex%c\tr%12-15d, [%16-19R]"
      "setpan\t#%9-9d"
    
    Here, the '%d' escape is used with a bitfield modifier, '%12-15d' in
    the first instruction, and '%9-9d' in the second instruction, but,
    both of these are the '%d' escape.
    
    However, in the first instruction, the '%d' is used to print a
    register number, notice the 'r' immediately before the '%d'.  In the
    second instruction the '%d' is used to print an immediate, notice the
    '#' just before the '%d'.
    
    We have two problems here, first, the '%d' needs to know if it should
    use register style or immediate style, and secondly, the 'r' and '#'
    characters also need to be styled appropriately.
    
    The final thing we must consider is that some escape codes result in
    more than just a single operand being printed, for example, the '%q'
    operand as used in arm_opcodes ends up calling arm_decode_shift, which
    can print a register name, a shift type, and a shift amount, this
    could end up using register, sub-mnemonic, and immediate styles, as
    well as the text style for things like ',' between the different
    parts.
    
    I propose a three layer approach to adding styling:
    
    (1) Basic state machine:
    
        When we start printing an instruction we should maintain the idea
        of a 'base_style'.  Every character from the assembler string will
        be printed using the base_style.
    
       The base_style will start as mnemonic, as each instruction starts
       with an instruction mnemonic.  When we encounter the first '\t'
       character, the base_style will change to text.  When we encounter
       the first '@' the base_style will change to comment_start.
    
       This simple state machine ensures that for simple instructions the
       basic parts, except for the operands themselves, will be printed in
       the correct style.
    
    (2) Simple operand styling:
    
        For operands that only have a single meaning, or which expand to
        multiple parts, all of which have a consistent meaning, then I
        will simply update the operand printing code to print the operand
        with the correct style.  This will cover a large number of the
        operands, and is the most consistent with how styling has been
        added to previous architectures.
    
    (3) New styling syntax in assembler strings:
    
        For cases like the '%s' that I describe above, I propose adding a
        new extension to the assembler syntax.  This extension will allow
        me to temporarily change the base_style.  Some operands, like
        '%d', will then print using the base_style rather than using a
        fixed style.
    
        Here are the two examples from above that use '%d', updated with
        the new syntax extension:
    
          "ldrex%c\t%{R:r%12-15d%}, [%16-19R]"
          "setpan\t%{I:#%9-9d%}"
    
        The syntax has the general form '%{X:....%}' where the 'X'
        character changes to indicate a different style.  In the first
        instruction I use '%{R:...%}' to change base_style to the register
        style, and in the second '%{I:...%}' changes base_style to
        immediate style.
    
        Notice that the 'r' and '#' characters are included within the new
        style group, this ensures that these characters are printed with
        the correct style rather than as text.
    
        The function decode_base_style maps from character to style.  I've
        included a character for each style for completeness, though only
        a small number of styles are currently used.
    
    I have updated arm-dis.c to the above scheme, and checked all of the
    tests in gas/testsuite/gas/arm/, and the styling looks reasonable.
    
    There are no regressions on the ARM gas/binutils/ld tests that I can
    see, so I don't believe I've changed the output layout at all.  There
    were two binutils tests for which I needed to force the disassembler
    styling off.
    
    I can't guarantee that I've not missed some untested corners of the
    disassembler, or that I might have just missed some incorrectly styled
    output when reviewing the test results, but I don't believe I've
    introduced any changes that could break the disassembler - the worst
    should be some aspect is not styled correctly.
