llvm dev - Mar 2018 - Migration from 3.8 to 6.0 questions (segfault most concerning)

I'm encountering a few problems in my migration that I haven't yet
figured out.

`getOrInsertFunction` is generating a SEGFAULT at
FunctionType::isValidArgumentType(llvm::Type*).  I'm calling it as:

    generic_ptr_ = llvm::PointerType::get(
llvm::Type::getInt8Ty(context), 0 );
    f_natural_int = llvm::IntegerType::get(context, 64);
    module->getOrInsertFunction(
        "count_malloc", generic_ptr, f_natural_int, (llvm::Type*)0 );


It appears there is no more Reloc::Default or CodeModel::Default, but
the docs on those fields indicate there is still a target default. How
do I get the default relocation and codeModel?

I'm still using the legacy::PassManager. Is there a new way to do the
passes now?

There docs still reference `tool_output_file*`*, but it appears the new
name, in the header, is `ToolOutputFile`.

I found the problem with `getOrInsertFunction`. It's now using a C++
variadic template, thus I shouldn't provide the trailing null sentry.
Changing to this works:

    module->getOrInsertFunction("count_malloc", generic_ptr,
f_natural_int );

It looks like LLVM is being slowly C++ modernized, I do the same in my
code over time. :)
