The PowerPC backend has long promoted some floating-point vector operations (such as select) to integer vector operations. Unfortunately, this behavior was broken by r216555. When using FP_EXTEND/FP_ROUND for promotions, we must check that both the old and new types are floating-point types. Otherwise, we must use BITCAST as we did prior to r216555 for everything. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@228969 91177308-0d34-0410-b5e6-96231b3b80d8
