Patch: PR40900, extending call patterns

[Eric Botcazou]

> That would be good.

Very lightly tested.


	* expr.c (expand_expr_real_1) <SSA_NAME>: Fix long line.  Save the
	original expression for later reuse.
	<expand_decl_rtl>: Use promote_function_mode to compute the signedness
	of the promoted RTL for a SSA_NAME on the LHS of a call statement.
