* config/i386/i386.c (x86_64_sign_extended_value): Add allow_rip

	argument.  In CM_SMALL_PIC model consider SYMBOL_REFs binding locally or
	from constant pool or LABEL_REFs as sign extended if allow_rip.
	Change all +-1GB limits to +-16MB.
	(x86_64_general_operand, x86_64_szext_general_operand,
	x86_64_nonmemory_operand, x86_64_movabs_operand,
	x86_64_szext_nonmemory_operand, x86_64_immediate_operand,
	legitimate_address_p, ix86_expand_int_movcc): Update callers.
	(local_symbolic_operand): Don't allow offsets bigger than +-16MB
	in CM_SMALL_PIC model.
	(legitimate_pic_address_disp_p): Don't check offsets before
	calling local_symbolic_operand.
	(legitimize_pic_address): Force offsets bigger than +-16MB into
	register.
	* config/i386/i386.h (EXTRA_CONSTRAINT, CONST_COSTS): Likewise.
	* config/i386/i386-protos.h (x86_64_sign_extended_value): Update
	prototype.

	* configure.in: Test for @GOTNTPOFF and @INDNTPOFF on IA-32 too.
	Add x86-64 test.  Set tls_first_minor to 14 on IA-32 and x86-64.
	* configure: Rebuilt.
	* config/i386/i386.c (x86_64_sign_extended_value): Don't allow TLS
	SYMBOL_REFs unless enclosed in UNSPEC.  Handle UNSPEC_DTPOFF,
	UNSPEC_GOTNTPOFF and UNSPEC_NTPOFF.
	(legitimate_address_p): Allow foo@dtpoff(base) even on TARGET_64BIT
	-fpic.
	(ix86_encode_section_info): Don't ever generate TLSGD or TLSLD for
	non-pic code if TARGET_64BIT.
	(legitimize_address): Generate 64-bit TLS sequences.
	(output_pic_addr_const): Support x86-64 TLS operators.
	(i386_output_dwarf_dtprel): Output 64-bit DTPOFF as .long f@DTPOFF, 0.
	(print_operand_address): Use %fs instead of %gs on TARGET_64BIT.
	Don't append (%rip) in 64-bit TLSGD and TLSLD sequences.
	(output_addr_const_extra): Support x86-64 TLS operators.
	(maybe_get_pool_constant): Handle TARGET_64BIT -fpic.
	(ix86_tls_get_addr): Use __tls_get_addr on TARGET_64BIT
	unconditionally.

	(*tls_global_dynamic_32_gnu): ..., add !TARGET_64BIT.
