emulated tls.
* expr.c (emutls_var_address): New.
(expand_expr_real_1): Expand emulated tls.
(expand_expr_addr_expr_1): Likewise.
* libgcc-std.ver: Add __emutls_get_address, __emutls_register_common.
* output.h (emutls_finish): Declare.
* toplev.c (compile_file): Call it.
* tree-ssa-address.c (gen_addr_rtx): Check for const-ness of the
