Optimizer - Constant propagation for variables
...
* It doesn't work for function arguments at this point, but shouldn't be
too hard to implement that.
* Can't use it to its full potential mostly because I need to get rid of
the node-specific shit in the AST.

Horrible, spaghettish, slow, memory hungry but WORKING implementation of
use/define chains!!!!

Optimizer - UD chains - Function arguments
...
Function arguments are the simplest case for UD chains, as they are
immutable.

Optimizer - Edge types in CFG
...
Control flow graph edges have been assigned a type, which may be either
FLOW (for normal edges), CALL (for edges that enter a function) or RET
(for edges that exit a function). In addition, call sites have an
additional FLOW edge that bypasses the function call.

Optimizer - Refactored CFG construction
...
Split the control flow graph construction function into multiple
functions. Doesn't add anything to the code, but makes it slightly less
unreadable.

Optimizer - So, UD chains are broken
...
Disabled broken code and added some notes, which are probably broken as
well but fuck it.

Optimizer - Mostly OK use/define chain construction
...
In which "mostly" means that it will work, unless:
1/ something is used before being defined (will trigger assertion)
2/ a local variable is re-used before being redefined, which will
be detected as using the def from the previous execution (won't be a
problem for now as it'll crash first, due to (1))

Handles:

Doesn't handle as of yet:
