f25212a223 Don't create usless casts for same-bith-width floating point casts.

84f3eab017 Implement getIntegerCast and getFPCast for ConstantExpr. These are similar 
to the createIntegerCast and createFPCast for CastInst instructions.

6d81a7d2ae Implement createIntegerCast and createFPCast factory methods for handling 
integer and floating point cast creation. createIntegerCast generates
ZExt/SExt, BitCast or Trunc. createFPCast generates FPExt, Bitcast, or
FPTrunc.

it from the constant's type.

difference.
