More consistent access to sparc %ger register. 

* config/sparc/sparc.md (fpack16_vis, fpackfix_vis, fpack32_vis): Make
	GSR_REG an input operand to UNSPEC instead of a parallel USE.
	(faligndata<V64I:mode>_vis): Likewise and use DI mode.
	(alignaddrsi_vis, alignaddrdi_vis, alignaddrlsi_vis, alignaddrldi_vis):
	Reference GSR_REG in DI mode, simplify convoluted expressions by using
	zero_extract.
	(bshuffle<V64I:mode>_vis): Reference GSR_REG in DI mode.
