altivec.md (*altivec_lvx_<mode>_internal): Remove asterisk from name so this can be generated directly. 

2015-04-23  Bill Schmidt  <wschmidt@linux.vnet.ibm.com>

	* config/rs6000/altivec.md (*altivec_lvx_<mode>_internal): Remove
	asterisk from name so this can be generated directly.
	(*altivec_stvx_<mode>_internal): Likewise.
	* config/rs6000/rs6000.c (rs6000_emit_le_vsx_store): Add assert
	that this is never called during or after reload/lra.
	(rs6000_frame_related): Remove split_reg
	argument and logic that references it.
	(emit_frame_save): Remove last parameter from call to
	rs6000_frame_related.
	(rs6000_emit_prologue): Remove last parameter from eight calls to
	rs6000_frame_related.  Force generation of stvx instruction for
	Altivec register saves.  Remove split_reg handling, which is no
	longer needed.
	(rs6000_emit_epilogue):  Force generation of lvx instruction for
	Altivec register restores.
