Go binding: Add methods for missing PassManagerBuilder C APIs

[rhysd]

Summary

Hi team,

I found some APIs are lack in Go binding. So I added them as attached patch.
Added APIs are below:

• LLVMPassManagerBuilderPopulateLTOPassManager
• LLVMPassManagerBuilderSetDisableUnitAtATime
• LLVMPassManagerBuilderSetDisableUnrollLoops
• LLVMPassManagerBuilderSetDisableSimplifyLibCalls
• LLVMPassManagerBuilderUseInlinerWithThreshold

I created this patch against rL295310. LLVM and Go bindings can be built with this patch.

This is my first attempt to send a patch to LLVM.
So could you please point out if something is wrong. I'll fix it as soon as possible.

Thanks.
