Ok, then it might be difficult to land this to 22.x

This PR is the correct root-cause fix. Without static, _CLC_INLINE (inline) function in header is problematic in C: when function is not inlined in a TU, compiler assumes it will be provided by another file (which won't happen) and generates declaration for __clc_flush_denormal_if_not_supported in that TU.
