* c-convert.c (convert) [INTEGER_TYPE]: Drop ARG. Don't pass ARG to
ubsan_instrument_float_cast. Fold EXPR. Use NULL_TREE instead of
NULL.
* convert.c (convert_to_integer_1): Adjust call to
ubsan_instrument_float_cast. Use NULL_TREE instead of NULL.
* ubsan.c (ubsan_instrument_float_cast): Drop the ARG parameter. Use
EXPR instead of ARG.
* ubsan.h (ubsan_instrument_float_cast): Adjust declaration.
* gcc.dg/ubsan/float-cast-overflow-atomic.c: New test.
