1036 Make operand 0 input only, clobber it. Use UNSPEC, not a bogus
1037 MEM for program memory word reference. Do not add the label to
1038 the table index in each of the asm output templates, instead ...
1039 (casesi): ... do it in RTL. Adjust to match the above change.

1081 `reference' type, and then saying the stack slot has that
1082 reference type. This loses type information (breaking GDB's
1083 `ptype' command, among other things) just to describe a location
1084 which stabs can represent correctly in other ways.
