PR tree-optimization/59622
* gimple-fold.c (gimple_fold_call): Fix a typo in message. For
__builtin_unreachable replace the OBJ_TYPE_REF call with a call to
__builtin_unreachable and add if needed a setter of the lhs SSA_NAME.
Don't devirtualize for inplace at all. For targets.length () == 1,
if the call is noreturn and cfun isn't in SSA form yet, clear lhs.
