[TTI] Treat *l (long double) and *f128 (_Float128) libcalls the same

As noted in the preexisting FIXME above this hunk, the logic in this
function is not always accurate. However, the logic for `long double`
and `_Float128` should be approximately the same for these functions
(almost everything requiring a libcall), so it makes sense to treat them
the same.

This is meant to reduce churn in cases where `*l` and `*f128` lowerings
call to the same symbol so can be used interchangeably.
