vsx.md (VSX_L): Do not include IBM extended double 128-bit types...

2015-11-16  Michael Meissner  <meissner@linux.vnet.ibm.com>

	* config/rs6000/vsx.md (VSX_L): Do not include IBM extended double
	128-bit types, just types that fit in a single vector.
	* config/rs6000/rs6000.md (FMOVE128_GPR): Likewise.
