Add support for sparc VIS3 fp<-->int moves.

	* config/sparc/sparc.h (SECONDARY_MEMORY_NEEDED): We can move
	between float and non-float regs when VIS3.
	* config/sparc/sparc.c (eligible_for_restore_insn): We can't
	use a restore when the source is a float register.
	(sparc_split_regreg_legitimate): When VIS3 allow moves between
	float and integer regs.
	(sparc_register_move_cost): Adjust to account for VIS3 moves.
	(sparc_preferred_reload_class): On 32-bit with VIS3 when moving an
	integer reg to a class containing EXTRA_FP_REGS, constrain to
	FP_REGS.
	(sparc_secondary_reload): On 32-bit with VIS3 when moving between
	float and integer regs we sometimes need a FP_REGS class
	intermediate move to satisfy the reload.  When this happens
	specify an extra cost of 2.
	(*movsi_insn): Rename to have "_novis3" suffix and add !VIS3
	guard.
	(*movdi_insn_sp32_v9): Likewise.
	(*movdi_insn_sp64): Likewise.
	(*movsf_insn): Likewise.
	(*movdf_insn_sp32_v9): Likewise.

	(*movdf_insn_sp64_vis3): New insn.
	(*zero_extendsidi2_insn_sp64_vis3): New insn.
	(*sign_extendsidi2_insn_vis3): New insn.
	(TFmode reg/reg split): Make sure both REG operands are float.
	(*mov<VM32:mode>_insn): Add "_novis3" suffix and !VIS3 guard. Remove
	easy constant to integer reg alternatives.
	(*mov<VM64:mode>_insn_sp64): Likewise.
	(*mov<VM64:mode>_insn_sp32_novis3): Likewise.
