compiler: refactor and add tests

Browse Source 
This commit finally introduces unit tests for the compiler, to check
whether input Go code is converted to the expected output IR.

To make this necessary, a few refactors were needed. Hopefully these
refactors (to compile a program package by package instead of all at
once) will eventually become standard, so that packages can all be
compiled separate from each other and be cached between compiles.
