Change build files to generate and compile C++ file with LLVM IR as C array. The LLVM IR files are now generated as a dependency of the codegen module, rather than separately. The IR files are kept in the same location as before, but are not required at runtime. Also change suffix from .ll (which is meant to be for the human-readable text IR) to .bc (the correct extension for LLVM bitcode). Includes a modified script file2array.sh from the Apache-licensed Swift/T project that generates a valid C++ source file with binary data encoded as an array variable. Also enable and fix CMake rules to generate the IR metadata, instead of doing it in make_impala.sh.
