  Log Message:
  -----------
  [OpenCL] Do not guard vload/store_half builtins

The vload*_half* and vstore*_half* builtins do not require the
cl_khr_fp16 extension: pointers to `half` can be declared without the
extension and the _half variants of vload and vstore should be
available without the extension.

This aligns the guards for these builtins for
`-fdeclare-opencl-builtins` with `opencl-c.h`.
