cpp_get_token. Use reached_end_of_context and
consume_next_token_from_context. Unify its return point. Move
the location tweaking from cpp_get_token_with_location in here.
(cpp_get_token): Use cpp_get_token_1

contexts.

Pass it to replace_args and to the "used" cpp callback. Get the
number of function-like macro arguments from funlike_invocation_p,
pass it to the new delete_macro_args to free the memory used by
macro args. When -ftrack-macro-expansion is in effect, for macros
that have no arguments, create a macro map for the macro expansion
and use it to allocate proper virtual locations for tokens
resulting from the expansion. Push an extended tokens context
containing the tokens resulting from macro expansion and their
virtual locations.
(replace_args): Rename the different variables named 'count' into
variables with more meaningful names. Create a macro map;
allocate virtual locations of tokens resulting from this
expansion. Use macro_arg_token_iter to iterate over tokens of a
given macro. Handle the case of the argument of
-ftrack-macro-expansion being < 2. Don't free macro arguments
memory resulting from expand_arg here, as these are freed by the
caller of replace_arg using delete_macro_args now. Push extended
token context.
(next_context, push_ptoken_context, _cpp_push_token_context)
(_cpp_push_text_context): Properly initialize the context.
(expand_arg): Use the new alloc_expanded_arg_mem,
