  [AMDGPU][clang] provide device implementation for __builtin_logb and … (#129347)

…__builtin_scalbn

Clang generates library calls for __builtin_* functions which can be a
problem for GPUs that cannot handle them. This patch generates call to
device implementation for __builtin_logb and ldexp intrinsic for
__builtin_scalbn.
