Allow CONCATs in emit_group_load_1.

This one line patch is a pre-requisite to a solution to PR target/123506;
an effort to improve middle-end code for returning structures.  Currently,
emit_group_load_1 contains code to handle a CONCAT returned by force_reg.
This tweak avoids the call for force_reg if the source is already a CONCAT,
which allows this subroutine to be re-used by target-specific implementations
of emit_group_load.  Many thanks to Jeff Law for cross-platform testing.

	* expr.cc (emit_group_load_1): Don't call force_reg if orig_src
	is already a CONCAT.
