Run against all passing tests in PureScript compiler test suite

[felixSchl]

All of these tests should eventually pass using this backend: https://github.com/purescript/purescript/tree/master/tests/purs/passing.

The directory structure is set up such that every (NAME).purs file is a test with additional supporting modules optionally residing in a folder named (NAME)/ in the same directory.

The logic for this already exists for the most part: https://github.com/felixSchl/purescript-c/blob/5ccdd0584d856584259096eadd11d316375f476d/test/Main.purs#L49-L57.

• Resolve dependencies (do all tests just rely on prelude?)
• Compile Makefiles (Generate Makefiles #13)
• Generate test suite using purescript-spec (each test case should become an it block)

Everything's set up now to work through the tests fixing anything that comes up. The biggest problem now is not having implemented the FFI of many of the dependencies. This is where fun becomes work and contributions would be very welcomed.

We're starting to look really good. @Lupino do you feel up to doing more? I am thinking of taking a stab at purescript-st next.

[felixSchl]

I've created a number of issues and an encompassing project. If you want to work on any of the issues please make sure it's not already assigned.

Yay, we're 239/266 tests passing! A few sigsegvs here (likely stack overflows) and a few sigabrt there (likely failed asserts), a missing implementation for ObjectUpdate, a few missing FFIs for tests themselves, as well as a missing implementations for purescript-arrays (#36), purescript-strings (#34), and we'll be there before we know it!

[felixSchl]

We're at 255/266 with @Lupino's work on purescript-arrays. Almost there! :)

[felixSchl]

We're at 256/266 as of 993d1fd.

What's next: I think the missing FFI tests will fall relatively quickly, but there's some corefn parsing issues which might cause a larger hold up, for example: paulyoung/purescript-corefn#57.

This is done.
