re PR c++/17412 (tree check failure in fold-const)
PR c++/17412
* fold-const.c (fold): Do not try to fold the operand of a
CLEANUP_POINT_EXPR if that operand does itself not have any
operands.
testsuite/
* g++.dg/parse/break-in-for.C: New test.
PR middle-end/17417
* langhooks.c (lhd_decl_printable_name): Make sure that this
function is called with is a decl node that has an identifier.
* tree-pretty-print.c (dump_function_name): New function to
wrap PRINT_FUNCTION_NAME and dump_decl_name.
(print_call_name): Use it.
