Unify new_symbol and new_symbol_full

This patch unifies new_symbol with new_symbol_full, replacing a
wrapper function with a default parameter.

2018-01-17  Tom Tromey  <tom@tromey.com>

	* dwarf2read.c (dwarf2_compute_name): Update comment.
	(read_func_scope, read_variable): Update.
	(new_symbol): Remove.
	(new_symbol_full): Rename to new_symbol.
