1. Corrected for `fpext f16->f64` case
according to checks in `LowerFP_EXTEND`:
```
assert((!Subtarget->hasFP64() || !Subtarget->hasFPARMv8Base()) &&
"With both FP DP and 16, any FP conversion is legal!");
```
if both features are enabled we can mark it Legal and mark Custom otherwise.
3. For `f128->f32` case `fptrunc` will be softened anyway, since f128 is not
legal.
