I tried to make it clear that it relates to __fp16 and not _Float16, like in
Type.h:
```
bool isHalfType() const; // OpenCL 6.1.1.1, NEON (IEEE 754-2008 half)
bool isFloat16Type() const; // C11 extension ISO/IEC TS 18661
```
It's all a bit confusing with all the different names for f16 types. Half seems
to relate either to the LLVM I/R type, or to the ARM __fp16 type.
HasLegalHalfType refers to LLVM I/R, while HalfArgsAndReturns relate to ARM
(IIUC).
