* Upon entering a new body, the local scope variables are collected.
* VM instruction PushLocal now uses a `Local` value instead of a `Sym`
value
* Compilation of a new AST body will implicitly create a new scope

* Basic are a more linear way of representing code. Thunks beget basic
blocks, which beget vectors of instructions.
* Basic blocks are also being flattened into a vector of instructions
(hopefully, no tests done yet)
* OH yeah locals can be collected too (but currently are not being
collected in the compiler, that should come soon)

Some instructions are currently implemented. Others are not. This is
mostly just a checkpoint so I can implement lexical name definitions.

While I like the idea of having a runtime completely decoupled from the
syntax and compiler, I don't think this is that big of a project for
that to be necessary or even useful yet.
