[LLVMdev] Vararg Intrinsics still supported?

LLVM never supported varargs intrinsics, i.e. it never supported things like
   llvm.wonder_intrinsic(...)
What is does support is intrinsic overloading, where you can have a version
of wonder_intrinsic that takes a float argument, another that takes an i32
argument etc.  It does this by giving each such version of the intrinsic a
different name, by appending the type to the name.

Ciao, Duncan.
