[compiler] Readability refactor of comilation pipeline.

This is a pure refactoring CL and should not contain any functional
changes to the code. The following has been done:
- Group compiler.cc into sections for each component.
- Surround local helper methods by anonymous namespace.
- Move implementation of Compiler (API class) together.
