* eh-common.h: Remove NEW_EH_MODEL compile time flag, and replace with
flag_new_exceptions runtime flag.
(struct old_exception_table): New struct which represents what
the exception table looks like without the new model.
(NEW_EH_RUNTIME): New value used as a tag in the exception table to
flag that this is a new style table.
* except.h: Remove compile time flag NEW_EH_MODEL.
(expand_builtin_eh_stub_old): New prototype.
* tree.h (enum built_in_function): Add BUILT_IN_EH_STUB_OLD.
* expr.c (expand_builtin): New builtin func BUILT_IN_EH_STUB_OLD.
* c-decl.c (init_decl_processing): Add new builtin function
__builtin_eh_stub_old.
* final.c (final_scan_insn): Replace compile time flag NEW_EH_MODEL.
* flags.h (flag_new_exceptions): New runtime flag.
* toplev.c (flag_new_exceptions): Initialize default to 0,
-fnew-exceptions sets to 1.
* except.c (output_exception_table_entry): Output New style exception
identifier into table, and replace compile time flag NEW_EH_MODEL
with runtime flag flag_new_exceptions.
(output_exception_table): Replace compile time flag NEW_EH_MODEL.
(expand_builtin_eh_stub_old): Duplicates original functionality of
expand_builtin_eh_stub.
(expand_builtin_eh_stub): Replace compile time flag NEW_EH_MODEL.
* libgcc2.c (find_exception_handler): Remove NEW_EH_MODEL #ifdefs.
(old_find_exception_handler): New func, same as find_exception_handler
except it works on the old style exception table.
(__throw): Replace NEW_EH_MODEL. Detect new model based on presence
of identifier in the exception table, and call appropriate routines.

* except.c (init_exception_processing): Remove NEW_EH_MODEL compile
time flag. Call __cp_eh_info instead of __cp_exception_info.
* exception.cc (struct cp_eh_info): Remove NEW_EH_MODEL flag.
(__cp_exception_info): Return offset into cp_eh_info structure to
match what use to be the start of this structure.
(__cp_eh_info): New function to return a pointer to cp_eh_info struct.
(__cplus_type_matcher, __cp_push_exception): Remove NEW_EH_MODEL
compile time flag.
(__uncatch_exception, __check_eh_spec, std::uncaught_exception): Call
__cp_eh_info instead of __cp_exception_info.
