These functions are all mapped to LLVM intrinsics.
The clspv and spirv targets don't declare or define any of these CLC
functions, and instead map these to their corresponding OpenCL symbols.
Increase fp16 support to allow clspv to continue to be OpenCL compliant
following the update of the OpenCL-CTS adding more testing on math
functions and conversions with half.
Math functions are implemented by upscaling to fp32 and using the fp32
implementation. It garantees the accuracy required for half-precision
float-point by the CTS.
Passes CTS on carrizo (when forced to use sw fma) and turks.

Passing values less than 0 to the llvm.sqrt() intrinsic results in
undefined behavior, so we need to check the input and return NaN if
is is less than 0.

There are two implementations of nextafter():
1. Using clang's __builtin_nextafter. Clang replaces this builtin with
a call to nextafter which is part of libm. Therefore, this
implementation will only work for targets with an implementation of
libm (e.g. most CPU targets).
2. The other implementation is written in OpenCL C. This function is
known internally as __clc_nextafter and can be used by targets that
don't have access to libm.
