Probably this code is unneeded since non GOT-related TLS relocations are skipped by the bolt in rewriteinstance.cpp: handleRelocation routine, search for Relocation::isTLS(RType) there. So it would just stay as imm value and would be emitted by the bolt with this value. At list it seems these switch-cases could be merged in *MOVW_UABS* relocations handle below
