Timotej Kapus b99ed0163e [OCaml] Handle nullptr in Llvm.global_initializer 
LLVMGetInitializer returns nullptr in case there is no initializer.
There is not much that can be done with nullptr in OCaml, not even
test if it is null. Also, there does not seem to be a C or OCaml API
to test if there is an initializer. So this diff changes
Llvm.global_initializer to return an option.

type 'a t
type any = [ `Module | `Function ]
(** [PassManager.create ()] constructs a new whole-module pass pipeline. This
type of pipeline is suitable for link-time optimization and whole-module
transformations.
See the constructor of [llvm::PassManager]. *)
val create : unit -> [ `Module ] t
(** [PassManager.create_function m] constructs a new function-by-function
pass pipeline over the module [m]. It does not take ownership of [m].
This type of pipeline is suitable for code generation and JIT compilation
tasks.
See the constructor of [llvm::FunctionPassManager]. *)
val create_function : llmodule -> [ `Function ] t
(** [run_module m pm] initializes, executes on the module [m], and finalizes
all of the passes scheduled in the pass manager [pm]. Returns [true] if
any of the passes modified the module, [false] otherwise.
See the [llvm::PassManager::run] method. *)
val run_module : llmodule -> [ `Module ] t -> bool
(** [initialize fpm] initializes all of the function passes scheduled in the
function pass manager [fpm]. Returns [true] if any of the passes modified
the module, [false] otherwise.
See the [llvm::FunctionPassManager::doInitialization] method. *)
val initialize : [ `Function ] t -> bool
(** [run_function f fpm] executes all of the function passes scheduled in the
function pass manager [fpm] over the function [f]. Returns [true] if any
of the passes modified [f], [false] otherwise.
See the [llvm::FunctionPassManager::run] method. *)
val run_function : llvalue -> [ `Function ] t -> bool
(** [finalize fpm] finalizes all of the function passes scheduled in the
function pass manager [fpm]. Returns [true] if any of the passes
modified the module, [false] otherwise.
See the [llvm::FunctionPassManager::doFinalization] method. *)
val finalize : [ `Function ] t -> bool
(** Frees the memory of a pass pipeline. For function pipelines, does not free
the module.
See the destructor of [llvm::BasePassManager]. *)
val dispose : [< any ] t -> unit
