Remove support for demangling GCC 2.x era mangling schemes.
* cplus-dem.c: Remove cplus_mangle_opname, cplus_demangle_opname,
internal_cplus_demangle, and all subroutines.
(libiberty_demanglers): Remove entries for ancient GNU (pre-3.0),
Lucid, ARM, HP, and EDG demangling styles.
(cplus_demangle): Remove 'work' variable. Don't call
internal_cplus_demangle.

To demangle it -# correctly, I believe that we have to understand that the J37J deep -# in the string somehow refers back to the type starting 37 characters -# in from some starting point, so that it winds up being the type -# starting with 41THandle.... However, lacking a spec for EDG -# demangling, it's hard to implement this. -# -# In the meantime, this symbol can be successfully demangled in GNU -# mode. Of course the result is more or less nonsense, but an older -# version of g++ would indeed generate this mangled name given the -# appropriate input, so the demangling is correct. ---format=auto --no-params -__CPR212____ct__Q3_3std141list__tm__128_Q2_3edm41THandle__tm__26_Q2_4emid15EMparticleChunkQ2_3std68allocator__tm__51_Q2_3edmJ37J14const_iteratorFRCQ3_3std18list__tm__7_Z1ZZ2Z8iterator -_Z1ZZ2Z::__CPR212____ct__Q3_3std141list__tm__128_Q2_3edm41THandle__tm__26_Q2_4emid15EMparticleChunkQ2_3std68allocator__tm__51_Q2_3edmJ37J14const_iteratorFRCQ3_3std18list__tm(iterator) -_Z1ZZ2Z::__CPR212____ct__Q3_3std141list__tm__128_Q2_3edm41THandle__tm__26_Q2_4emid15EMparticleChunkQ2_3std68allocator__tm__51_Q2_3edmJ37J14const_iteratorFRCQ3_3std18list__tm -# # This used to cause a crash.
