Go binding leaks CreateGlobalVariable().
And I have tried to write this manually, but I am wondering why don't go
binding implement this API?:

package llvm

/*
#include "IRBindings.h"
#include <stdlib.h>
*/
import "C"
import (
        "unsafe"
)

type DIGlobalVariable struct {
        Name        string
        Linkage     string
        File        Metadata
        Line        int
        Type        Metadata
        LocalToUnit bool
        Expr        Metadata
        Decl        Metadata
        AlignInBits uint32
}

func (d *DIBuilder) CreateGlobalVariable(scope Metadata, v DIGlobalVariable)
Metadata {
        name := C.CString(v.Name)
        linkage := C.CString(v.Linkage)
        defer C.free(unsafe.Pointer(name))
        result := C.LLVMDIBuilderCreateGlobalVariableExpression(
                d.ref,
                scope.C,
                name, C.size_t(len(v.Name)),
                linkage, C.size_t(len(v.Linkage)),
                v.File.C,
                C.unsigned(v.Line),
                v.Type.C,
                C.LLVMBool(boolToCInt(v.LocalToUnit)),
                v.Expr.C,
                v.Decl.C,
                C.uint32_t(v.AlignInBits))
        return Metadata{C: result}
}
