Trevor Gross 6fb6c19c96 Replace f16 and f128 pattern matching stubs with real implementations
This section of code depends on `rustc_apfloat` rather than our internal
types, so this is one potential ICE that we should be able to melt now.

This also fixes some missing range and match handling in `rustc_middle`.
