[llvm-commits] [PATCH] Add bindings for walking the instruction stream.

[Erick Tryzelaar]

Use some of the new features that gordonh provided. However, I don't think
we need to use everything:

Since the LLVMGetLastInstruction actually returns one past the last
instruction that is mainly used for c++style iteration. Since we already
have to protect against next_instr and etc from returning a null pointer,
 we can already model "last_instr" as "None".

I don't think we need position_builder as proposed. It's more of a
convenience function so that you don't have to write "match next_instr i
with ...", but I don't think you need it that often, and it's trivial to
write a function in the client to do that for us. I've added a couple
wrapper scripts that (I think) would be more common, position_at_start and
position_after, that will also safely handle builders without any
instructions in them.

Finally, I migrated a couple functions from llvm_ocaml.c to llvm.ml. While
this probably doesn't make a difference, it might allow ocaml to do some
more optimizations.
