re PR tree-optimization/91162 (ICE: tree check: expected class 'type', have 'exceptional' (error_mark) in useless_type_conversion_p, at gimple-expr.c:86 (error: invalid 'PHI' argument))

PR middle-end/91162
* tree-cfg.c (move_block_to_fn): When releasing a virtual PHI
node make sure to replace all uses with something valid.
* gcc.dg/autopar/pr91162.c: New testcase.
