tcg/tci: Make tci_tb_ptr thread-local
Each thread must have its own pc, even under TCI.
Remove the GETPC ifdef, because GETPC is always available for
helpers, and thus is always required. Move the assignment
under INDEX_op_call, because the value is only visible when
we make a call to a helper function.
