re PR bootstrap/77993 (bootstrap failure on PowerPC/Linux)

Browse Source 
2016-11-03  Michael Meissner  <meissner@linux.vnet.ibm.com>

	PR target/77993
	* config/rs6000/rs6000.h (FLOAT128_IBM_P): Do not allow IFmode or
	ICmode unless we have standard PowerPC floating point.
	* config/rs6000/rs6000.md (FP iterator): Likewise.
	(FMOVE128 iterator): Likewise.
