re PR c++/7112 (Regression: ICE on C++ code involving templates and sizeof)
PR c++/7112
* g++.dg/template/sizeof2.C: New test.
PR c++/7112
* mangle.c (write_expression): Add mangling for sizeof when
applied to a type.
* operators.def: Remove stale comment.
* cp-demangle.c (demangle_operator_name): Add type_arg parameter.
Set it for the "st" operator.
(demangle_expression): Handle expressions with types as arguments.
