Demangler update?

[Ken Block USG]

H.J. submitted this patch for the demangler a while back and it has not
been checked in. The patch provides:

1) support for GNAT ada compiler.
2) adds a --style switch to a number of tools to allow them to specify
which demangler to be used.
3) It adds the ability to dynamic load a demangler that is shipped
independently.


Compaq C++ depends on this patch. What needs to be done to get this
demangler patch checked in?  If I redid this patch against the latest
snapshot and broke it down into smaller pieces, would somebody be
willing to check it in?
