gcc/:
	* doc/gimple.texi: Fix quoting of multi-word return values in
	@deftypefn statements.  Ensure presence of return value.  Wrap
	overlong @deftypefn lines.
	(is_gimple_operand, is_gimple_min_invariant_address): Remove
	descriptions of removed functions.
	* doc/hostconfig.texi (Host Common): Wrap long line, fix quoting
	of multi-word return value in @deftypefn statement.
