[PATCH] sparc-tdep.c: Fix `return' and `finish' from stop in call dummy

[Peter.Schauer]

Committed (the first part of the patch has been approved by David Taylor
in private mail, the second part has been approved by Michael Snyder).

	* sparc-tdep.c (sparc_fix_call_dummy):  Improve comments.
	Adjust call_dummy_breakpoint_offset, so that `finish' after a stop
	in a call dummy works.
	(sparc_gdbarch_init):  Fix setting of pc_in_call_dummy, it depends
	on SPARC32/64_CALL_DUMMY_ON_STACK, not DO_CALL_DUMMY_ON_STACK.
