[libclc] Add __clc_nan implementation with signed nancode argument (#146485)

Browse Source 
In OpenCL Extended Instruction Set Specification, nancode can be signed
integer or vector of signed integers values.
This PR has no change to amdgcn--amdhsa.bc and nvptx64--nvidiacl.bc
because the newly added clc functions are not used in OpenCL library.
