Patch to fix sibcall v. postincrement

[Jason Merrill]

Fixes g++.other/badopt1.C, where we assign the result of a call to an
expression containing a postincrement.  The increment was only being
emitted in one of the alternate call forms, which was not chosen.

	* calls.c (expand_call): emit_queue if we're trying a sibcall.
