The llvm c-api contains LLVMBuildNeg but not LLVMBuildFNeg. I've attached a simple patch which adds LLVMBuildFNeg.
I know it's a little late, but it'll be great if this can be added for the 2.6 release. I'm asking because I'd like to add support for FNeg in llvm-py too, and it'll be hard to do that if llvm 2.6 doesn't have it.
