x86_64: Fix fp-to-core conversion
Long max value cannot be represented with double precision
and check fp against max_long does not guard invocation of
conversion instruction. As a result conversion ends up with
min long instead of max long.
The patch changes the guard check to not allow conversion
instruction for max long.
