The compiler may add a suffix to a mangled name. A typical example would be splitting a function and creating a ".cold" variant. This patch changes Ada decoding (aka demangling) to handle these suffixes. It also changes the encoding process to handle them as well. A symbol like "function.cold" will now be displayed to the user as "function[cold]". The "." is not simply preserved because that is already used in Ada.
