This gets rid of the muladd errors due to not raising the invalid flag.

- Before:
Errors found in f64_mulAdd, rounding near_even, tininess before rounding:
+000.0000000000000  +7FF.0000000000000  +7FF.FFFFFFFFFFFFF
        => +7FF.FFFFFFFFFFFFF .....  expected -7FF.FFFFFFFFFFFFF v....
[...]

- After:
In 6133248 tests, no errors found in f64_mulAdd, rounding near_even, tininess before rounding.
[...]
