Compilation Warning resulting from non-trivial half precision type (MacOS build, homebrew gcc-10)

[bjoo]

Hi,
As discussed in my MacOS documentation PR, the compilation gives a warning related to using memcpy to copy a non-trivial type used for half precision

/Users/36j/Devel/HIP-CPU/HIP-CPU/examples/bit_extract/../../include/hip/hip_fp16.h:898:43:   required from here
/Users/36j/Devel/HIP-CPU/HIP-CPU/examples/bit_extract/../../include/hip/../../src/include/hip/detail/helpers.hpp:46:32: warning: 'void* memcpy(void*, const void*, size_t)' copying an object of non-trivial type 'class half_float::half' from an array of 'const short int' [-Wclass-memaccess]
   46 |                     std::memcpy(&r, &v, sizeof(T));
      |                     ~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~

This appearst to be known (and is benign) I am just noting it here for later cleanup.
