Options

sparc.c (sparc_override_options): If not TARGET_FPU, turn off TARGET_VIS.

	TARGET_FPU, turn off TARGET_VIS.
	* config/sparc/sparc.h (TARGET_SWITCHES): Add no-vis.
	(LEGITIMATE_CONSTANT_P): Allow SF/DF mode zero when TARGET_VIS.
	* config/sparc/sparc.md (movsi_insn): Use fzeros not fzero.
	(movdi_insn_sp64): Add VIS fzero alternative.
	(clear_sf, clear_df): New VIS patterns.
	(movsf, movdf expanders): Allow fp_zero_operand flat out when
