Quentin Colombet d6dbec4c6f [X86] Fix the lowering of TLS calls. 
The callseq_end node must be glued with the TLS calls, otherwise,
the generic code will miss the uses of the returned value and will
mark it dead.
Moreover, TLSCall 64-bit pseudo must not set an implicit-use on RDI,
the pseudo uses the symbol address at this point not RDI and the
lowering will do the right thing.
