I know that using the LLVMBuilder was useful to me in the early days of
my work with LLVM to see exactly how the IR matched with what I expected
it to given the input. It's only now that I'm working on global
variables that require ConstantExpr types for initialisers that I
started to use the LLVMFoldingBuilder.
I'll work on the patch and submit it here when it's ready.
