We do already have Constant::isZeroValue(). There's also m_SpecificFP

[LLVMdev] Inverse of ConstantFP::get and similar functions?
Hi,
I noticed that ConstantFP::get automatically returns the appropriately
types Constant depending on the LLVM type passed in (i.e. if called
with a vector, it returns a splat vector with the given constant).
Is there any simple way to do the inverse of this function? i.e.,
given a llvm::Value, check whether it is either a scalar of the given
constant value or a splat vector with the given
