* c-typeck.c (convert_for_assignment, c_finish_return): For
-fsanitize=float-cast-overflow casts from REAL_TYPE to integer/enum
types also set in_late_binary_op around convert call.
* c-convert.c (convert): For -fsanitize=float-cast-overflow REAL_TYPE
to integral type casts, if not in_late_binary_op, pass c_fully_fold
result on expr as last argument to ubsan_instrument_float_cast,
if in_late_binary_op, don't use c_save_expr but save_expr.
