Don't you need LLVMContext.h for the LLVMContext instance below?

Apparently it is included from one of the other files. Adding it back to make it
clear that we are using it.

-#include "llvm/Assembly/AssemblyAnnotationWriter.h"
 // Note: We need the following to provide the API for calling the NaCl
 // Bitcode Writer to generate the frozen file.
 #include "llvm/Bitcode/NaCl/NaClReaderWriter.h"
 // Note: We need the following to provide the API for calling the (LLVM)
 // Bitcode Reader to read in the corresonding pexe file to freeze.

do you need intrinsicinst.h?
