So, here's the patch to tear out the old code, which passes the GCC
regression testsuite. I also tried building binutils/gdb with it, and
both will need to remove code that calls cplus_mangle_opname for dealing
with the old mangling scheme.

-
- demangle_signature -- demangle the signature part of a mangled name
-
-SYNOPSIS
-
- static int
- demangle_signature (struct work_stuff *work, const char **mangled,
- string *declp);
-
-DESCRIPTION
-
- Consume and demangle the signature portion of the mangled name.
-
- DECLP is the string where demangled output is being built. At
- entry it contains the demangled root name from the mangled name
- prefix. I.E. either a demangled operator name or the root function
- name. In some special cases, it may contain nothing.
-
- *MANGLED points to the current unconsumed location in the mangled
- name. As tokens are consumed and demangling is performed, the
- pointer is updated to continuously point at the next token to
- be consumed.
-
- Demangling GNU style mangled names is nasty because there is no
- explicit token that marks the start of the outermost function
- argument list. */

-
- Otherwise, we prepend "class::" to the current DECLP.
-
- Reset the constructor/destructor flags once they have been

-LOCAL FUNCTION
-
- get_count -- convert an ascii count to integer, consuming tokens
-
-SYNOPSIS
-
- static int
- get_count (const char **type, int *count)
-
-DESCRIPTION
-
- Assume that *type points at a count in a mangled name; set
- *count to its value, and set *type to the next character after
- the count. There are some weird rules in effect here.
-
- If *type does not point at a string of digits, return zero.
-
- If *type points at a string of digits followed by an
- underscore, set *count to their value as an integer, advance
- *type to point *after the underscore, and return 1.
-
- If *type points at a string of digits not followed by an
- underscore, consume only the first digit. Set *count to its
- value as an integer, leave *type pointing after that digit,
- and return 1.
-
- The excuse for this odd behavior: in the ARM and HP demangling
- styles, a type can be followed by a repeat count of the form
- `Nxy', where:
-
- `x' is a single digit specifying how many additional copies
- of the type to append to the argument list, and
-
- `y' is one or more digits, specifying the zero-based index of
- the first repeated argument in the list. Yes, as you're
- unmangling the name you can figure this out yourself, but
- it's there anyway.
-
- So, for example, in `bar__3fooFPiN51', the first argument is a
- pointer to an integer (`Pi'), and then the next five arguments
- are the same (`N5'), and the first repeat is the function's
- second argument (`1').

- Note that g++ bases its type numbers starting at zero and counts all
- previously seen types, while lucid/ARM bases its type numbers starting
- at one and only considers types after it has seen the 'F' character
- indicating the start of the function args. For lucid/ARM style, we
- account for this difference by discarding any previously seen types when
- we see the 'F' character, and subtracting one from the type number
- reference.
