	* config/i386/i386.md (*tls_global_dynamic_64_largepic): New insn.
	(*tls_local_dynamic_base_64_largepic): Likewise.
	(tls_global_dynamic_64_<mode>, tls_local_dynamic_base_64_<mode>):
	Remove predicate from call operand.
	* config/i386/i386.c (ix86_tls_get_addr): For -mcmodel=large -fpic
	return sum of pic_offset_table_rtx and UNSPEC_PLTOFF of the symbol.
