Casting 'constant float' to 'constant [4 x i8]' causes assertion failure:

Assertion `SrcBitSize == DstBitSize && "BitCast requies types of same width"'
failed.

Test case:


   Constant* c = ConstantFP::get(Type::FloatTy, float(1.0));
   c = ConstantExpr::getBitCast(c, ArrayType::get(Type::Int8Ty,
gTargetData->getTypeSize(c->getType())));

gTargetData is a global created with code like:

   gTargetData = new llvm::TargetData(M);

where module M has:

   target datalayout =
"e-p:64:64:64-i1:8:8-i8:8:8-i16:16:16-i32:32:32-i64:64:64-f32:32:32-f64:64:64-v64:64:64-v128:128:128-a0:0:8"
   target triple = "x86_64-unknown-linux-gnu"

set from code.

Hope that is enough.
