// Design of Compiler
//===----------------------------------------------------------------------===//
// 1. A compiler instance can be constructed provided an "initial config."
// 2. A compiler can later be re-configured using config().
// 3. Once config() is invoked, it'll re-create TargetMachine instance (i.e.,
// mTarget) according to the configuration supplied. TargetMachine instance
// is *shared* across the different calls to compile() before the next call
// to config().
// 4. Once a compiler instance is created, you can use the compile() service
// to compile the file over and over again. Each call uses TargetMachine
// instance to construct the compilation passes.
