Ivan A. Kosarev 1b7851212b [NEON] Define fp16 vld and vst intrinsics conditionally 
This patch fixes definitions of vld and vst NEON intrinsics so
that we only define them if half-precision arithmetic is
supported on the target platform, as prescribed in ACLE 2.0.

Silviu Baranga 3102a01258 [ARM] Guard the declarations of f16 to f32 vcvt intrinsics in arm_neon.h by testing __ARM_FP 
Summary:
Conversions between float and half are only available when the
taraget has the half-precision extension. Guard these intrinsics
so that they don't cause crashes in the backend.

Fixes PR27550.
