`f128` intrinsic functions from libm sometimes lower to `long double` library calls when they instead need to be `f128` versions. Add a generic test demonstrating current behavior.

It forces expensive verification outside EXPENSIVE_CHECKS builds. Should not be enabled unless you are specifically fixing an issue that triggers machine verifier errors.
